Disabling the bugzilla sync script

The bugzilla sync script has started choking because of failing to add/modify a higher number of entries. Several people have set up their bugzilla accounts to use email addresses, which don't match the owners.list files in cvs [anymore]. Please fix this! I've also contacted these people privately. Until the files will be fixed, the bugzilla sync script cron job is not running anymore. [...] I understand that if RPM Fusion duplicated all of Fedora's infrastructure including FAS, pkgdb, bugzilla+xmlrpc, koji, bodhi, it might be easier to not forget about old-style owners.list files. However, as long as that stuff is not being offered, please be gentle with the available resources and try to keep the owners.list files accurate.
