nethack4: use upstream patch for install layout
openttd 1.4.2
brogue 1.7.4

Directory hierarchy changed a bit.  Original tarball extracts as 'brogue-linux-1.7.3/brogue-1.7.3/' and the new one extracts as 'brogue-1.7.4/'.  The tarball itself also changed from '.tar.gz' to '.tbz2' .

Closes #133.

Since the nethack4 maintainers do a lot of development on HEAD and don't
do releases that often, I thought it would be a good idea to have the
option of installing via HEAD.
