selftests/bpf: Support ppc64el in vmtest 

With a rootfs built using libbpf's BPF CI [1], we can run specific tests
as follows:

$ ../libbpf-ci/rootfs/mkrootfs_debian.sh --arch ppc64el --distro noble
$ PLATFORM=ppc64el CROSS_COMPILE=powerpc64le-linux-gnu- \
    tools/testing/selftests/bpf/vmtest.sh \
    -l libbpf-vmtest-rootfs-*-noble-ppc64el.tar.zst \
    -- ./test_progs -t verifier_array_access

Does not include a DENYLIST or support for KVM for now.
