Bug#613912: ghostscript ships its own fonts in libgs9-common, additionally depends on gsfonts

The most true source will be the ghostscript release tarball as soon as
they reverted back to the original fonts. Why should we package the fonts
from a separate release tarball from 200x when they are already part of
the recent gostscript distribution anyway?
