Force libc6 dependency version.
Drop explicit libelf-dev install command, as it should be pre-installed by
Travis CI already, according to .travis.yaml.

S50-run-tests uses -e, which means that it immediately exits on test
failures without writing /exitcode. Fix by temporarily turning -e off.
Another issue is that $? in S50-run-tests is not quoted, which causes
the random value from the host to be taken (in practice always 0), so
fix that as well.
Finally, this fix has a positive side effect - QEMU no longer hangs
when tests fail. This is because rcS (generated by mkrootfs.sh) also
uses -e and immediately exits, if one of the scripts that it calls
fails, without calling S99-poweroff.
Example output after the fix:
Summary: 53/184 PASSED, 5 SKIPPED, 1 FAILED

It requires v5.9+ kernel when the test code is built with a newer
toolchain. The support was added by commit b33164f2bd1c ("bpf:
Iterate through all PT_NOTE sections when looking for build id").

Clang 13 regressed BPF code generation causing some of BPF selftests to fail.
Until that is mitigated, stick to version 12.

Clang 13 became the new nightly version, so switch to it. Also do vmlinux
compilation with a bit more parallelism. And account python-docutils
installation as part of selftests build.

Selftests makefile deletes local bpf_testmod.ko, so that invalidates current
approach of faking bpf_testmod.ko "generation". Instead, generate a fake
Makefile that will create an empty bpf_testmod/bpf_testmod.ko.

Non-latest kernel versions don't build kernel from sources, so module buliding
fails, despite using `make prepare`. For now, just make sure no module is
built by overwriting bpf_testmod/Makefile.

test_progs's IMA selftests requires extra Kconfig values, so update
latest.config to accommodate those.

tcpbpf_user uses cgroup bpf_link, not available in 5.5. hash_large_key is
testing a more permissive verifier check, implemented in 5.11. So blacklist
both.

Blacklist new tests that are depending on features in latest kernel. Also
temporarily blacklist raw_tp_test_run test, until it is fixed upstream.

Attempt to first fetch bpf-next tree from a snapshot, falling back to shallow
clone, and if that is not enough, doing a full bpf-next clone. This should
both improve a speed and (because of full clone fallback) improve test
reliability if libbpf wasn't synced in a while.

Blacklist btf_map_in_map permanently for 5.5. bpf_verif_scale is broken due to
Clang issues on latest. Do not run ALU32 flavor for test_progs on 4.9.0, which
doesn't support ALU32 yet.

Whatever happened, clang-11 and llvm-11, to which clang/llvm packages resolve,
respectively, are not there anymore. Seems like clang-12/llvm-12 are the
latest now, but for whatever reason clang/llvm don't resolve to them yet.
Hard-code version 12 for now.

Drop blacklist and instead use a small whitelist of tests that are still
supposed to work on old 4.9 kernel.

Make sure that libbpf sanitizes BTF properly for older kernels.
Add a stage for 4.9.0 kernel in TravisCI.
For now make test failures non-blocking by adding 4.9.0 to `allow_failures`
section.
Blacklist is copy-pasted 5.5.0 kernel blacklist.
Now that pre-generated vmlinux.h is used for compilation of non-latest tests,
we don't need custom adjustments for 5.5 kernel selftests. Adjust blacklist
now that those new self-tests are built into test_progs.

Manually generate vmlinux.h based on latest.config to be used for non-latest
selftest build. This will keep bpftool and newest selftests builds succeeding,
while at runtime blacklist will skip them.
