The vmtest action is used by several workflows: test, pahole, ondemand.
At the same time, vmtest action requires valid access rights to /dev/kvm
and is the only action that uses it.
This commit moves /dev/kvm permissions setup from test workflow to
vmtest action, in order to make sure that setup logic is shared by all
workflows that run vmtest.
Should fix CI failures like [1].

s390 tests are executed on selfhosted runner using root user,
avoid setting /dev/kvm permissions in such case.
This should fix CI failures like [0].
(Still necessary for x86 tests executed on standard github runners).

Starting recently libbpf CI runs started failing with the following
error:
##[group]vm_init - Starting virtual machine...
Starting VM with 4 CPUs...
INFO: /dev/kvm exists
KVM acceleration can be used
Could not access KVM kernel module: Permission denied
qemu-system-x86_64: failed to initialize KVM: Permission denied
##[error]Process completed with exit code 2.
E.g. see here [0]. The error happens because CI user has not enough
rights to access /dev/kvm. On a regular machine the solution would be
to add user to group 'kvm', however that would require a re-login,
which is cumbersome to achieve in CI setting.
Instead, use a recipe described in [1] to make udev set 0666 access
permissions for /dev/kvm.

Having too new build environment in workflows that build selftests on
the host, but run them in a separate QEMU image can lead to problems
with runtime linker complaining about missing new enough version of
glibc and other dependencies.
Until we update images, fix used Ubuntu version to ubuntu-20.04 to
mitigate.

The runners are having their labels uniformized across architecture.
z15 is being removed in favor of s390x.

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we currently use, has been superseded.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.

Run it on the self-hosted builder with tag "z15".
Also add the infrastructure code for the self-hosted builder.

Make sure we run all of the tests even if some of them fail. This allows to
test all of them independently, especially kernel LATEST slow test.
