Add target to build a dmg containing Rockbox Utility, ipodpatcher and
sansapatcher as single app bundle, and create a more fancy dmg using
dmgbuild.

To use ipodpatcher and sansapatcher as external binaries (so we can do
proper permission elevation) we need to build them using qmake as part
of the main build. Add a subdirs template based project file to do that,
and project files for the patchers.
Move Linux appimage rules one level up, since it needs to include the
patchers as well.
