sandbox: use debian:jessie, add filesystem test, make image smaller

1. Don't use FROM golang, this gives more control over the versions that
are used.

2. Compress calls into one layer and remove bootstrap after it's used,
along with other unnecessary files. Saves about 500 MiB:
playground/sandbox                         703.3 MB
us.gcr.io/golang-org/appengine/sandbox.17  1.216 GB

I think more work can be done here.

3. Add a test for the fake filesystem.
