rm: update gnulib to get an fts fix for Cygwin+NWFS/NcFsd file systems

* NEWS (Bug fixes): Mention it.
As far as we know, this fix affects only Cygwin with NWFS or NcFsd
file systems.  See these:
http://git.sv.gnu.org/cgit/gnulib.git/commit/?id=71f13422f3e634
http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/28739
http://cygwin.com/ml/cygwin/2011-10/msg00365.html
* src/system.h (ENODATA): Remove fall-back definition, now that
gnulib provides one.  Caught by the sc_prohibit_always-defined_macros
syntax-check rule.
Also remove now-irrelevant "Don't use bcopy..." comment.

 ** Bug fixes
 
+  rm -rf DIR would fail with "Device or resource busy" on Cygwin with NWFS
+  and NcFsd file systems.  This did not affect Unix/Linux-based kernels.
+  [bug introduced in coreutils-7.0, when rm began using fts]
+
   tac no longer fails to handle two or more non-seekable inputs
   [bug introduced in coreutils-5.3.0]
