Remove the MIME type calls and queries from the search engine

	* gtk/gtksearchenginebeagle.c:
	* gtk/gtksearchenginesimple.c:
	* gtk/gtksearchenginetracker.c: Remove the MIME type calls and
	queries from the search engine implementations, since we use our
	own GtkFileSystem to filter out basing on MIME types and we cannot
	query MIME types anyway. The GtkQuery private object still has
	MIME type, as well as location, support for future expansion.
