Fix for conflict resolution of virtual packages + better removal of packages

Fixed virtual package resolution so that virtual package
provider with highest score is choosen. Previously apt
chose first available package from list. This caused apt
to fail to resolve certain conflict situations. We encountered
this problem when we tried to create images for specific
variants in our system composition environment.

Go through the chain of installed packages and make sure that
packages that should not be installed are removed. This a particual
problem that shows up when working with or-packages.
