ghostscript: debloat

ghostscript builds a monolithic gs executable by default.
when we build it so libgs.so is created as well, we get 2 other
binaries, which are command line compatible.

ghostscript ships with a lot of dependencies in-tree,
we need to remove them so the system ones are picked up instead.
add cups-filters
add a couple perl packages required for git-send-email
