Improve desktop environment detection.

UNKNOWN now means generic unix theme, rather than Gtk: there
are other KDE/Qt-based desktops, and there's also the case of
no desktop at all (e.g. bare Xvfb, as used by automated builds).

To make this correct for GTK-based desktops, this commits improves
the detection of the current desktop environment.
