*: drop {gtk,qt}-recordmydesktop subdirs

This restores the recordmydesktop/ subdir as root from the mirror I
cloned by fork from.

I have no particular interest in the gtk/qt frontends and it doesn't
appear they were part of a single tree in the past.  But I will
probably preserve backwards compatibility of the cli so they can
continue to work with this fork installed.
