* Pin dependencies in docker file. The docker file had two dependencies that were not locked. An npm dependency and the debian base image. This PR pins those two dependencies. * Use the slim version of debian image. * Use image with bigger disk to build docker images. * remove web_engine_tests from cirrus.

Cirrus Linux
Flutter's Linux tasks run on a custom Docker image. The Dockerfile for this
image can be found at /dev/ci/docker_linux/Dockerfile.
On each new change to this Dockerfile, Cirrus will build a new version of
the Docker image as a dependency to any Linux tests. It is no longer necessary
to manually build and push the Docker image locally.
NOTE: there are some factors external to the actual Dockerfile that would
necessitate rebuilding the Docker image, such as upstream code changes, (Linux
distribution) repository updates or a file that gets COPYied into the image
changing. In this case, a trivial Dockerfile change (such as a comment)
would invalidate the cache and trigger a rebuild.
