posix: Make posix_spawn extensions available by default 

Some sources merely include <spawn.h> without -D_GNU_SOURCE and expect
declarations for posix_spawn_file_actions_addchdir_np to be available.
For consistency, declare posix_spawn_file_actions_addfchdir_np,
posix_spawn_file_actions_addclosefrom_np,
posix_spawn_file_actions_addtcsetpgrp_np as well.
