```
fix child process spawn on macos hangs issue

When a child process with stdin, stdout behavior set to pipe is
ran on macos it used to hang which has been fixed. Issue existed because
we forgot to call `posix_spawn_file_actions_addclose` syscall on user
exposed file descriptor which resulted on file descriptor not closing
properly.
