package/cups-filters: fix ln -r workaround for older distributions

Browse Source 
Add a patch to create the ln-srf script that was not included in the 1.25.6
release tarball.  Also add a post-patch hook to ensure that the script is
executable, since GNU patch < 2.7 does not handle the git patch permission
extensions.
