So far the vmtest.sh script, which can be used as a convenient way to
run bpf selftests, has obtained the kernel config safe to use for
testing from the libbpf/libbpf GitHub repository [0].
Given that we now have included this configuration into this very
repository, we can just consume it from here as well, eliminating the
necessity of remote accesses.
With this change we adjust the logic in the script to use the
configuration from below tools/testing/selftests/bpf/configs/ instead
of pulling it over the network.

Migration of vmtest to libbpf/ci will change the address
of INDEX in vmtest.sh, which will cause vmtest.sh to not
work due to the failure of rootfs fetching.

[1] added s390 support to libbpf CI and added an ${ARCH} prefix to a
number of paths and identifiers in libbpf GitHub repo, which vmtest.sh
relies upon. Update these and make use of the new s390 support.

Increase memory to 4G, 8 SMP core with host cpu passthrough. This
make it run faster in parallel mode and more likely to succeed.

The newly introduced -s command line option starts an interactive shell.
If a command is specified, the shell is started after the command
finishes executing. It's useful to have a shell especially when
debugging failing tests or developing new tests.
Since the user may terminate the VM forcefully, an extra "sync" is added
after the execution of the command to persist any logs from the command
into the log file.

When vmtest.sh ran a command in a VM, it did not record or propagate the
error code of the command. This made the script less "script-able". The
script now saves the error code of the said command in a file in the VM,
copies the file back to the host and (when available) uses this error
code instead of its own.

The script runs the BPF selftests locally on the same kernel image
as they would run post submit in the BPF continuous integration
framework.
The goal of the script is to allow contributors to run selftests locally
in the same environment to check if their changes would end up breaking
the BPF CI and reduce the back-and-forth between the maintainers and the
developers.
