net-print/cups-filters: add --disable-{foomatic,ghostscript} support

Support a new USE flag to allow disabling ghostscript-based filters in a
CUPS installation. Requires patching in a new --disable-ghostscript
option to the configure script. Patch supplied in upstream bug:

https://bugs.linuxfoundation.org/show_bug.cgi?id=1342

Also support a proper configure flag for foomatic at the same time.
