posix: Fix pidfd_spawn/pidfd_spawnp leak if execve fails (BZ 31695)
If the pidfd_spawn/pidfd_spawnp helper process succeeds, but evecve fails for some reason (either with an invalid/non-existent, memory allocation, etc.) the resulting pidfd is never closed, nor returned to caller (so it can call close). Since the process creation failed, it should be up to posix_spawn to also, close the file descriptor in this case (similar to what it does to reap the process). This patch also changes the waitpid with waitid (P_PIDFD) for pidfd case, to avoid a possible pid re-use. Checked on x86_64-linux-gnu. Reviewed-by: Carlos O'Donell <carlos@redhat.com>
