Minimum dev container setup

This includes two fixes to allow the configure.sh script to work.

- Use `patch` instead of `git apply` to apply the Ceres patch as this proved
  more consistently reliable.
- Reset the terminal state before the `installpython` step as it assumes the
  working directory is `/code` which isn't true outside of the docker build.

The devcontainer is deliberately kept minimal and can be extended as needed. So
far this reliably can build ODM but I haven't attempted to run it yet.
