A docker environment to test scrcpy @ brunoais/scrcpy-docker

As I wanted to be able to compile scrcpy in a controlled environment, I decided to make one myself.
Because I find it quite useful to use, I decided to improve the scripts I made so others can also make use of it.

You can find the results @ https://github.com/brunoais/scrcpy-docker

All info I consider relevant is in its README file.

Expect new feature suggestions coming out soon.

Start by reviewing the external scrcpy-docker repository and its README, which the issue identifies as the source of the proposed environment. The issue does not define a change within scrcpy or a concrete completion condition, so the desired scope would need to be clarified before implementation.
