gitlab CI: name the qemu tags per distribution
Having only one qemu tag worked only because we only had one distribution using qemu. If we have multiple of those we just duplicate/overwrite the variable so let's not do that.
Due to an influx of spam, we have had to impose restrictions on new accounts. Please see this wiki page for instructions on how to get full permissions. Sorry for the inconvenience.
GitLab will be down for maintenance Monday June 03, from approx 10am UTC for roughly 48 hours. This is for a major gitlab upgrade which requires a DB migration. See the tracker issue for more informations.
