Switch from CMD to ENTRYPOINT, then use exec in both start.sh scripts, so process id 1 can be the process it needs to be, as this is what gets SIGTERM on docker compose down.

We now get a .bashrc by default, so switch the logic to detecting the custom PS1 before putting it in .bashrc.
Account for a directory that steamcmd expects.
