Bug#732440: ghostscript: Error: /typecheck in /findfont with fonts-font-awesome installed

[Mike Miller <mtmiller@debian.org>]

Control: tags -1 + patch

Fixed in upstream git now [1], patch adapted and included inline below
applies cleanly to the current Debian package and works there as well.
Please consider applying this patch to the next source update, otherwise
will be fixed in ghostscript 9.11 when that is released.

Subject: [PATCH] Bug 695031: don't assume we can read a font file

When we scan system fonts, we were assuming fonts found would be in a format
Ghostscript understands. This is not necessarily the case.

So put the minimal parsing call to get the font's name in a stopped context,
so we can skip the file it's not an understandable format. And clean up the
stack in the event we try such a file.

No cluster differences.
