ts-xen-build-prep: Run the backgrounded resize2fs with ionice

We wrap this in
  ionice -cBest-Effort -n7

This is an attempt to stop resize2fs from starving builds of IO
bandwidth.  We have been seeing that some IO-intensive build steps
(notably, configure) can take unreasonable amounts of time and we
suspect resize2fs as the culprit.
