[PATCH bpf-next 2/2] selftests/bpf: Verify program FD after non-autoload programs in lskel

["Thiébaud Weksteen" <tweek@google.com>]

In test_global_percpu_data.c, dump_percpu_data is defined after two
non-autoload SEC("?kprobe") programs (verifier_strncmp and
verifier_snprintf). Verify in test_global_percpu_data_lskel() that
lskel->progs.dump_percpu_data.prog_fd is properly populated (> 0) when
loaded via the light skeleton.

Fixes: 4c9241bd731a ("selftests/bpf: Add tests to verify global percpu data")
Fixes: 1ed2294b31fc ("selftests/bpf: Test verifier log for global percpu data")
