[bug#26988] Add desktop-file-utils to all gtk applications

A profile hook checks manifest entries for some condition, then usually
adding a item to the profile's united output.

In case of the current 'xdg-desktop-database', it checks if any entry
has a reference of glib, then adding the 'mimeinfo.cache' to the

Yeah, the hook only run once for all the packages in the profile.
