Rax hosts uses qemu software emulated VMs without leveraging the
magic with-in the processors to help ensure speedy execution.
As such, they can be substantially slower in some operations, such
decompressing ramdisks. This adds an unpredictable element into our
CI and causes job failures when they should ahve succeeded, which
causes more rechecks, which consumes more resources... and the cycle
continues.
So instead, we'll extend the timeout a little, to hopefully give the
job time to complete without causing failures.
