Revert "ghostscriptX: update from 9.06 to 9.14, potentially fixes CVE-2012-4405"

This reverts commit 13fab57d127bf70a338901b422da32e562d16889.

Hopefully fixes the printing tests at
http://hydra.nixos.org/build/14952070/log/raw ; if not, it's probably
gutenprint although I doubt:

client# lp: Unsupported document-format "application/pdf".
cmplayer: fix build
xen: note about security for next bump
linux-man-pages: Update to version 3.73.
