rbutil: Add project file for building multiple binaries.

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.
