gnu: diffutils: Fix Gnulib/getopt cross-compilation issue.

Previously cross-compilation would fail:

     CC       xvasprintf.o
   xstrtol-error.c:50:16: warning: 'struct rpl_option' declared inside parameter list
		   int exit_status)
		   ^
   xstrtol-error.c: In function 'xstrtol_error':
   xstrtol-error.c:84:5: error: invalid use of undefined type 'struct rpl_option'

* gnu/packages/patches/diffutils-getopt.patch: New file.
* gnu/packages/base.scm (diffutils)[source]: Use it.
* gnu/local.mk (dist_patch_DATA): Add it.
