Run more jobs in parallel if we have enough loop devices.

By default, Linux ships with 8 loop devices, so we limit to 1 job
on those machines just to conserve six of the loop devices for other
processes. On buildbots, we've increased the number of loop devices to
64, so we should be able to run more jobs in parallel (up to 29 jobs,
if we have that many CPUs.)

BUG=chromium-os:19085
TEST=Run test suite with more loop devices and see it run faster.
