Mark internal unistd functions hidden in ld.so
Since internal unistd functions are only used internally in ld.so and
libc.so, they can be made hidden.  __close, __getcwd, __getpid,
__libc_read and __libc_write can't be hidden in ld.so on Hurd since they
will be preempted by the ones in libc.so after bootstrap.

	[BZ #19122]
	* include/unistd.h [IS_IN (rtld)]: Include <dl-unistd.h>.
	* sysdeps/generic/dl-unistd.h: New file.
	* sysdeps/mach/hurd/dl-unistd.h: Likewise.
