Core Xorg libraries necessary for Ghostscript now included

Until now, in order to build Ghostscript, the project used the host's Xorg
libraries. This was because we hadn't yet added the necessary build rules
for them.

With this commit, the instructions to build the necessary Xorg libraries
for Ghostscript have also been added. Also, the shared Ghostscript library
has been built with this commit and two sets of standard fonts are also
included, setting us on the path to build TeXLive from source later.

This task was done with the help and support of Raul Infante-Sainz.
