run-on-arch-action is simply a wrapper around docker. There is no
value in using it in libbpf, as it is not complicated to run
non-native arch docker images directly on github-hosted runners.
Docker relies on qemu-user-static installed on the system to emulate
different architectures.
Recently there were various reports about multi-arch docker builds
failing with seemingly random issues, and it appears to boil down to
qemu [1]. I stumbled on this problem while updating s390x runners [2]
for BPF CI, and setting up more recent version of qemu helped.
This change addresses recent build failures on s390x and ppc64le.

Track ubuntu-latest where relevant and possible.
We can't update to ubuntu-latest when building and running BPF
selftests, though, because our QEMU image has too old of an GLIBC.

The current version of actions/checkout is v3. That means that v2, which
we currently use, has been superseded. Update the version we use
accordingly.
