[COMMITTED PATCH] Move nss directory into sysdeps Subdirs.

[Roland McGrath]

The nss subdirectory (getent) depends on things only built into libc if the
inet subdirectory is built.  So it doesn't make much sense to build nss
without inet.

	* Makeconfig (all-Depend-files): Add existing
	$(sorted-subdirs:=/Depend) files.
	(all-subdirs): Remove nss.
	* sysdeps/unix/inet/Subdirs: Add it here instead.
	* hesiod/Depend: New file.
