[Buildroot] [git commit branch/2020.05.x] support/docker: drop Python 2.x modules

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=7aa6bbf6c9eeb36c365cb8187e12bd981f175570
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2020.05.x

Since commit 4a40d36f131890941c1e482eb5f28ebcd81cb7a3
("support/testing: switch to Python 3 only") our runtime testing
infrastructure is Python 3.x only.

Therefore, it is no longer needed to have python-nose2 and
python-pexpect in the Docker container used to run our Gitlab CI jobs.
