[Feature Request] Add sudo package and default password

AsteroidOS is currently in the process of adding support for wifi. This means we have an unsecured user shell, and even worse, a completely unsecured root shell. It is worth adding a default password to provide a bare minimum example of security.

It's also not the best practice to force the user to actually log in as root - it's common for users to log in as root (eg. to upgrade packages) and then forget and continue working in a vulnerable root shell. A sudo package is already available in oe-core, it seems like this is worth adding.
