Always define off_t, mode_t, pid_t

Browse Source 
* io/fcntl.h: Always define mode_t, off_t, pid_t and use these
	types for creat, creat64, lockf, posix_fadvise, posix_fallocate.
	[__USE_LARGEFILE64 && !__off64_t_defined]: Define off64_t.
	[__USE_LARGEFILE64]: Use off64_t in declaration of lock64,
	posix_fadvise64, posix_fallocate64.

* sysdeps/unix/sysv/linux/x86/bits/fcntl.h (F_GETLK, F_SETLK)
(F_SETLKW) [__x86_64]: Remove, provided by <bits/fcntl-linux.h>.
