Add logic to run from baked images.

Change adds the following:
- logic to run from "baked images". See [GVISOR_DIR]/tools/images
- installers which install modified files from a workspace. This
allows users to run benchmarks while modifying runsc.
- removes the --preemptible tag from built GCE instances. Preemptible
instances are much more likely to be preempted on startup, which
manifests for the user as a failed benchmark. I don't currently have
a way to detect if a VM has been preempted that will work for this
change.
