[Buildroot] [git commit branch/2018.02.x] ghostscript: security bump to version 9.25

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=fe98673790ca8fb13f04709ee062b3774f70256f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.02.x

Fixes the following security issues:

- CVE-2018-16543: In Artifex Ghostscript before 9.24, gssetresolution and
  gsgetresolution allow attackers to have an unspecified impact

- CVE-2018-17183: Artifex Ghostscript before 9.25 allowed a user-writable
  error exception table, which could be used by remote attackers able to
  supply crafted PostScript to potentially overwrite or replace error
  handlers to inject code.
