Title: become_a_nobody: call setgid and initgroups to update group list.

Without this patch gmond is (usually) run just as a ganglia user in root group and all system services that need to be monitored must be accessible by ganglia:root. With the patch the ganglia user can be added to groups that provide access to the required resources. In any case running the gmond process with root's groups is usually not the desired behavior.
