Modify setup.sh and build.sh to work with multiple ubuntu versions.

This removes the need for multiple build.sh and setup.sh files.

 ### Building from source using the Unreal Engine Editor for earlier versions of Ubuntu (e.g., Ubuntu 18.04)
 Instead of running the simulator from release binaries, you can compile it manually using unreal engine.
