[PATCH] Add systemtap privileged fedrawhide worker and builder

["Serhei Makarov" <serhei@serhei.io>]

Hello,

I'd like to commit the following patch (or something similar) to the sourceware builder config
and get a buildbot vm hooked up, so we can start taking our SystemTap buildbots and
test results public.

As one of the steps, could I have a worker pw for 'systemtap-fedrawhide-x86_64-privileged'?

All the best,
      Serhei Makarov

This is an initial commit to see how well my SystemTap buildbots would
work with the Sourceware builder infrastructure and public bunsen
instance. If all goes well, it will be possible to expand the public
testing setup to cover multiple distros and architectures.

The fedrawhide worker is an exclusive vm for full-privileged systemtap
testing (hence other builder runs should not be scheduled on it).
