[pitivi] Drop use of old "glib" module

[Colin Walters <walters src gnome org>]

commit da87a41ce112bd2521812ae7665e6fe6c347e4d4
Author: Colin Walters <walters verbum org>

    Drop use of old "glib" module
    
    It's not shipped in gnome-continuous, and we were just using
    it for markup_escape_text which works fine via gi.repository.GLib.
