 Revbump library users of ghostscript

 After the ghostscript update in 947d9823ca, the install name of the
 ghostscript library changed. All dependents need to be rebuilt against
 the new libgs.dylib, so revbump them.

 This list has been generated using 'port echo depends:ghostscript'.
 I have manually excluded ports that only had a runtime dependency (as
 opposed to a library dependency), assuming they would only need the
 binary. I have also excluded ports with library dependencies that only
 seem to use the 'gs' binary (e.g. because they declare
 depends_skip_archcheck for ghostscript).
