This approach creates all ${LOCALBASE} and ${X11BASE} desktop directories
before updating the desktop database to ensure the mimeinfo.cache files
are created when this package is installed.
Upon package deinstallation, each desktop directory will be rmdir'd.
* Move to a LOCALBASE PREFIX since gnome-vfs support was removed
* Cleanup leftover mimeinfo.cache files
* Make more portlint-friendly
