Use rootpw for setting the root password instead of user

Browse Source 
Ends up you cannot use the kickstart user command on root, since it
already exists, so we have to translate that into a rootpw command.

So [[customizations.user]] with name = "root" only support key, which
will set the ssh key, and password which will use rootpw to set the
password. plain text or encrypted are supported.
