Merge #512: Fix release builds docker container

6f926e6 Revert bad to using Debian stretch for docker (Andrew Chow)
efb2e02 Also install qt5 in docker container (Andrew Chow)
873386f Update pyenv commands for new behavior (Andrew Chow)

Pull request description:

  Repairs the docker container used for release builds

  * Pyenv made some changes to how it is activated, update the pyenv commands to match those
  * Downgrade to Debian stretch to fix #506. Stretch uses an older glibc. Somehow this change does not reintroduce #480
  * Install `qt5-default` in the container. Pyinstaller now seems to be having some problems with missing libraries when qt5 is not installed.
