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.
