games-simulation/simutrans: silence svn and git warnings

This commit sets svn to 0 and removes the check. The check could never
have been 1, because we are not in an svn. For the same reason it also
sets GIT_HASH to nothing instead of trying to run git.

The svn revision is supplied in the ebuild, because it is needed for
network games.
