[PATCH bpf-next v1 10/19] selftests/bpf: Fix include of <sys/fcntl.h>

[Tony Ambardar <tony.ambardar@xxxxxxxxx>]

Update ns_current_pid_tgid.c to use '#include <fcntl.h>' and avoid compile
error against mips64el/musl libc:

  In file included from .../prog_tests/ns_current_pid_tgid.c:14:
  .../include/sys/fcntl.h:1:2: error: #warning redirecting incorrect #include <sys/fcntl.h> to <fcntl.h> [-Werror=cpp]
      1 | #warning redirecting incorrect #include <sys/fcntl.h> to <fcntl.h>
        |  ^~~~~~~
  cc1: all warnings being treated as errors

Fixes: 09c02d553c49 ("bpf, selftests: Fold test_current_pid_tgid_new_ns into test_progs.")
