Here is a diff to update games/ezquake to 3.6.6. I had to move to github
/releases/ because upstream official supports release tarballs only, and
I experienced a teaminfo bug when using DIST_TUPLE.

see: https://github.com/QW-Group/ezquake-source/pull/1026

The release tarball contains version.json and qwprot (so no need for git
submodules and no need for network access).

Alternatively, we could host our own tarball using this script that
creates the release tarball.
see: https://github.com/QW-Group/ezquake-source/blob/master/dist/gen-release.sh

This diff:
- updates to 3.6.6
  changelog: https://github.com/QW-Group/ezquake-source/releases/tag/3.6.6
- moves back to release tarball using a combination of SITES and
  DISTNAME. it also defines DISTFILES. only release tarballs are
  officially supported.
- installs binary from ${WRKBUILD}/ezquake
- updates patch for CMakeLists.txt

This builds with the new cmake split port, but I had to uninstall my
old cmake before installing the new cmake. Team overlay works in my
testing connecting two clients to a ktx server.

Feedback and tests are welcome. OK?
