graphics/lua-gd: the port had been updated and improved (+)

- Update the version 2.0.33r3 (it's not tagged yet, but that's
  what written inside their Makefile) and unrestrict from the
  particular version of Lua (now we need to set PKGNAMEPREFIX)
- Simplify building: drop hand-rolled `do-build' target plus
  associated bits and use upstream routine, slightly adjusted
- Development now happens at GitHub, update MASTER_SITES and
  the WWW line in the port description accordingly
- Convert to option helpers and optimize some target recipes
