added amarok compile deps to Dockerfile
Added 5 new dependencies installed by default to compile amarok:
- dpkg-dev
- libmariadb-dev
- libloudmouth1-dev
- libfftw3-dev
- libtagc0-dev Feel free to reject if this isn't important enough to merge; I just ran into a lot of roadblocks figuring this out and didn't want others to do the same.
