[PATCH] localedef: improve error message [BZ #16985]

[Mike Frysinger]

If you pass in a path that fails to be opened, then output_path is set to
NULL, and an error is flagged.  Then at the end, we use both of those:
	cannot write output files to `(null)': No such file or directory

Tweak the message to use the user's input when output_path is NULL.

	[BZ #16985]
	* programs/localedef.c (main): Display argv[remaining] when
	output_path is NULL.
