Polish 'make install' support a bit

In particular:
  * Instead of replicating icons in the repository, install from src/res/oc.ico
  * Pack the game data
  * Remove runclonk script, install clonk binary only into bin/
    (this will make Clonk not run for the moment because it does not find
    its game data, but I intend to change that with a followup patch soon).
