Don't include sys/types.h from POSIX headers (1/n)
Many POSIX headers are including sys/types.h when they are only supposed
to expose a small number of types from that header. There will be several
patches in this sub-series; this one does the easiest cases.
* io/ftw.h: Don't include sys/types.h.
* misc/sys/uio.h: Don't include sys/types.h.
Include bits/types.h and bits/types/ssize_t.h.
Include stddef.h for size_t.
* posix/spawn.h: Don't include sys/types.h.
Include bits/types.h, bits/types/mode_t.h, and bits/types/pid_t.h.
* rt/aio.h: Don't include sys/types.h.
Include bits/types.h, bits/pthreadtypes.h, and bits/types/ssize_t.h.
Include stddef.h for size_t.
* sysdeps/pthread/semaphore.h: Don't include sys/types.h.
* sysdeps/unix/sysv/linux/bits/uio-ext.h: Use __pid_t, not pid_t.
* scripts/check-obsolete-constructs.py
(HEADER_ALLOWED_INCLUDES): Update.
