Maemo: Don't monopolize the debian directory.

Using a debian directory in the project root directory might interfere
with non-MADDE configurations.
We therefore introduce an extra directory qtc_packaging, where we can
safely put our stuff. In the future, this should also contain
non-Fremantle (and possibly non-Debian) configurations.
