gvisor: run bazel in a docker container

bazel has a lot of dependencies and users don't want to install them
just to build gvisor.

These changes allows to run bazel in a docker container.
A bazel cache is on the local file system (~/.cache/bazel), so
incremental builds should be fast event after recreating a bazel
container.

Here is an example how to build runsc:
make BAZEL_OPTIONS="build runsc:runsc" bazel
