Minor bug fix of v-sync-dns-cluster

Problem Outlined: It seems that another script has dropped a file called history.log into the $VESTA/data/users folder causing v-sync-dns-cluster to throw a soft error about not finding /usr/local/vesta/data/users/history.log/dns.conf when syncing zones.

Fix: Tell the script to ignore that log file when syncing user domains and the output becomes clean.
