[PATCH bpf-next 2/3] selftests/bpf: Move sys_pidfd_open() into test_progs.h

[Hou Tao <houtao@xxxxxxxxxxxxxxx>]

From: Hou Tao <houtao1@xxxxxxxxxx>

sys_pidfd_open() is defined twice in both test_bprm_opts.c and
test_local_storage.c, so move it to test_progs.h. And it will be used
in task_local_storage.c as well.
