ghostscript: Fix patch related build issues

The file ${S}/configure.ac is a symlink which seems to confuse some patch
application tools but not in all cases. Whilst I'd love to understand why
there is a difference, this fixes the build failures by applying the patch
to the real file rather than the symlink.
