Subject: [PATCH] Bug 700986: Remove the crazy md5 file copying nonsense

To preserve building as a standalone test exe, we avoided using Ghostscript
includes in the md5 source and header files, but dynamically add them to
copies of the files during the build. Since we no longer need/care for the
stand alone exe, remove the build complication, and just include the header
file normally.
