Buildslave disk space problems fixed

[Colin Finck]

Hi all!

We have run out of space on our temporary universal Build and ISO
machine HotelLux today. This is why TestCD creation has been failing.

I'm currently moving files away from the main disk to a temporary
storage. You should already be able to redo the failed builds.

Within this month, Aleksey and me will move the ISO storage back to our
actual storage server, upgraded with larger disks.
This one should be sufficient for quite some time.

Sorry for the inconveniences!

Cheers,

Colin
