Add logic to functions.prf and gyp_generator.prf
to invoke rcc from ninja as well.
Since we are building the whole library with ninja,
this is the only feasible way to get the dependencies right.

Changine the TEMPLATE of resources.pro from subdirs to aux,
since it is not building a library and not processing
subdirectories either.
