[CentOS-virt] Updated packages for XSA-156 to be built starting at 12:01am UTC

[George Dunlap]

As you may have noticed, XSA-156 is due to be released publicly at
12:01am tomorrow (10 November).

I've prepped packages, and before I leave today will set a script to
send them to the CBS at 12:01 exactly.  Packages should end up in
virt6-xen-44-candidate within probably half an hour after that.  If
something goes wrong, I'll try to have it sorted out when I come in
tomorrow morning (usually around 10am UTC).
