Merge lp:~adconrad/launchpad-buildd/speed-fixes into lp:launchpad-buildd

[Adam Conrad]

  * Shut up umount-chroot's verbose output, it served its purpose.
  * Yank out sbuild's dependency removal code, as we never once
    checked the return from this anyway, so it's just wasted time.
  * Stop writing to avg-space and avg-time, which we don't use.
