When building a subset of tracks, make sure new packages are added to
pbuilder even if the tracks that depend on them are not being built. To
achieve this, the information which tracks are to be built is now stored
as the do_build flag in the individual tracks and not by passing only a
subset of the tracks ot the PackagerGroup. Otherwise the PackagerGroup
would not determine the dependencies correctly.
