Update base to Ubuntu 20.04, Wine 7+.

Changes:
* base image migrated from 18.04 to 20.04.
* Remove Wine 5.x - <7.0 libfaudio0 patches. These are included in wine by defualt now.
* Reordered force_install_dir to be set before login, preventing execution halt with
  latest steamcmd release. See: ValveSoftware/steam-for-linux#8298
