Update Maemo packages (fixes #1148)

hildon-desktop is now compiled against gnome-menus-3. For some reason it's missing from Alpine, so I renamed and updated old gnome-menus2 package. It wasn't used by anything else in aports.

I didn't pick up the latest hildon-desktop 2.2.157.6 version yet, as I suppose maemo-leste/hildon-desktop@220b3e6f is going to cause breakage with current cogl package, which is compiled against desktop OpenGL (GLX) without EGL Xlib platform enabled.
