[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.

Thanks for the quick fix! I did rm -r ~/.bpf_selftest (though I thought I did that with my changes as well, whatever) before running vmtest.sh. It all worked. I got three test failures which is strange, because I don't get those failures in my custom and more complete QEMU image, so it's strange, if anyone has any ideas and is willing to help debug this, it would be greatly appreciated.
But either way, this fixes immediate problems with vmtest.sh, pushed to bpf-next. Thanks!
