Fix Docker build

This fixes the docker build, that was failing while installing N2VC due
to a new version of websockets that was released.

We specifically install the latest 4.x release of websockets, known to
be compatible with libjuju, in conjunction with a patch to N2VC that
specifies the version requirement.

Installing the specific version is necessary because websockets is being
installed as a dependency to another python library that is installing
5.0, but installing 4.1 satisfies its requirements.
