[gnome-software] Allow search-by-mimetype in the UI

[Richard Hughes <rhughes src gnome org>]

commit fce87155cf9c405bc653647675dcdd032c1f5acf
Author: Richard Hughes <richard hughsie com>

    Allow search-by-mimetype in the UI
    
    This means you get sensible results for queries like:
    
    $ gnome-software --mode=search --search-value="application/vnd.oasis.opendocument.text"
    
    Resolves part of: https://bugzilla.gnome.org/show_bug.cgi?id=707320
