[gtk+] Remove obsolete code to use a cached mime-type

[Benjamin Otte <otte src gnome org>]

commit 04c78019fb44f6e44ea055e20c201bcebed1050a

    Remove obsolete code to use a cached mime-type
    
    The non-standard "filechooser::mime-type" was a remnant of the recent-files code using
    a hand-built GFileInfo; now we just query the file info ourselves.
