on the offchance chpasswd breaks ownership...

The problem is that after this container is built, we have the correct users (now even with correct uid/gid but the folder `/home/vagrant` is owned by `root`, ergo the `vagrant` user cannot touch, rm or modify anything in the root of its own `$HOME`. Which is a shame really :crying_cat_face: 

This way the recursive `chown` is is the last thing that happens to the `vagrant` user. Hopefully will fix the home directory ownership issue.
