<broker> Updated spec file for correct user_action.log location
<oo-accept-broker> Added permission check for rest api logs

Spec was still referencing /var/log/openshift/user_action.log instead of
/var/log/openshift/broker/user_action.log this was causing the logfile
to be created with the wrong permissions when oo-accept-broker is run

oo-accept broker now checks for incorrect permissions for
user_action.log
