ghostscript: use system-wide openjpeg
The following error occurs when using `imagemagickBig`:

    $ ./result/bin/identify sample.jp2
    [1]    699089 IOT instruction (core dumped)  ./result/bin/identify sample.jp2

When looking at the call-trace it seems as if certain symbols, e.g.
`opj_malloc` are mixed up:

    #8  0x00007f78c79ad2f5 in MagickSignalHandler.cold () from /nix/store/bqy80qiw6czqh7vsmmmivwdswp9zzjgl-imagemagick-7.1.0-29/lib/libMagickCore-7.Q16HDRI.so.10
    #9  <signal handler called>
    #10 0x00007f78c5a6095f in opj_malloc () from /nix/store/wg6ly83k1k1fjiygiv1jr7li3p6dwsvq-ghostscript-with-X-9.55.0/lib/libgs.so.9
    #11 0x00007f78c5a60981 in opj_calloc () from /nix/store/wg6ly83k1k1fjiygiv1jr7li3p6dwsvq-ghostscript-with-X-9.55.0/lib/libgs.so.9
    #12 0x00007f78c4f48e24 in opj_create_decompress () from /nix/store/qwalb0kjz1p9c4j48qkk6ql47ds2lnhh-openjpeg-2.4.0/lib/libopenjp2.so.7

The `opj_create_decompress()` is called from the `openjpeg`-integration
of `imagemagick` and thus shouldn't affect `ghostscript` at all.
However, `ghostscript` (`libgs.so` to be precise) also exposes e.g.
`opj_malloc`:

    $ objdump -t /nix/store/wg6ly83k1k1fjiygiv1jr7li3p6dwsvq-ghostscript-with-X-9.55.0/lib/libgs.so.9.55|grep opj_malloc
    0000000000205940 g     F .text	000000000000002b              opj_malloc

Because of that, two incompatible symbols are used in the same process
and thus the `identify`-call breaks because the wrong one is used. To
work around that I decided to use the system-wide openjpeg instead.
I'm not sure why `libgs.so` wants to expose these symbols anyways, but
with that workaround the problem is solved.

Even though it's mentioned that ghostscript's openjpeg is heavily
patched, I think that this is somewhat outdated or at least irrelevant
considering that both ArchLinux[1] and Fedora[2] use the system-wide
`openjpeg` instead.

Ghostscript is the name of a set of tools that provides (i) an
interpreter for the PostScript language and the PDF file format,
(ii) a set of C procedures (the Ghostscript library) that
implement the graphics capabilities that appear as primitive
operations in the PostScript language, and (iii) a wide variety
of output drivers for various file formats and printers.
