Put /var/lib/mock on separate disk for live image build test

Browse Source 
The update live image build test keeps running out of disk space.
We've bumped the minimal disk image from 12GB all the way up to
20GB so far but it keeps happening. So let's try a different
strategy: use a scratch disk to mount /var/lib/mock. That's where
all the space gets used. This should allow us to reduce the size
of the minimal disk image again, and giving it 25GB of empty disk
should avoid it running out of space again for a while.
