icecream user on suse is 'icecream', not 'icecc'
fix location of suse logfiles

After the switch to make the daemon run as non-root user, it has no rights
to do anything in /var/log . These suse-specific changes were missed
in the commit that did the changes.
do not remove env. basedir itself

Since the change to run as non-root, the daemon cannot remove e.g.
/var/cache/icecream because of no rights to modify /var/cache.
do not chown() with root uid

The daemon no longer runs as root.
