misc: Added Dockerfile for Ubuntu 20.04

This Dockerfile creates an image which simulates an Ubuntu 20.04
environment. Unlike the Ubuntu 18.04 Dockerfile, this does not use
Python2. It uses exclusively Python3. Ubuntu 20.04 has Python3 installed
by default. The image this Dockerfile creates can be obtained from
"gcr.io/gem5-test/ubuntu-20.04_all-dependencies". To pull:

docker pull gcr.io/gem5-test/ubuntu-20.04_all-dependencies
