Subject: [PATCH] Have fc-cache remove invalid cache files from cache
 directories.

Old cache file versions, or corrupted cache files should be removed when
cleaning cache directories with fc-cache. This only affects filenames which
match the fontconfig cache file format, so other files will be left alone.
