Don’t require chown/chgrp for game installation

Problem reported by Joseph Mingrone in:
http://lists.gnu.org/archive/html/emacs-devel/2017-03/msg00622.html
* lib-src/Makefile.in (exp_archlibdir): Don’t fail if chown or
chgrp fails with update-game-score and the game directory.
Instead, expect the installer to fix this up afterwards.
