Reserve more memory for background processes.

Our build uses more memory now, so I've increased the base footprint
of our build from 7GB to 10GB. This reduces the number of parallel VMs
we can launch on machines with 12GB RAM from 2 to 1.

TEST=Test on buildbot with 12GB RAM and verify parallelism limit is 1 now
     rather than 2.
