Move /etc/group generation to the installer

This ensures that the gid's for the auto-generated user groups stay in
sync with the gid in /etc/passwd. It also makes it easier to evolve the
format of /etc/group in the future.

Support including other config files from a config file

See merge request !29

This will allow significantly reducing the amount of duplication

This will be necessary to handle including other configs from the config
to use as these configs will not be copied.

This is no longer used since redox!1397
