Hide __posix_spawn_file_actions_realloc/__spawni [BZ #18822]
Hide internal __posix_spawn_file_actions_realloc and /__spawni functions
to allow direct access within libc.so and libc.a without using GOT nor
PLT.
[BZ #18822]
* posix/spawn_int.h (__posix_spawn_file_actions_realloc): Add
attribute_hidden.
(__spawni): Likewise.
