Added file/user resources

Added file/user resources for $root and $user to satisfy Exec dependencies on like 49.  It's looking for puppet resources which ought to exist in this file.  Otherwise the including manifest must define them, which is not necessary IMO.

Avoids this error (where user is "vagrant"): 
Error: Could not find dependency File[/home/vagrant/.ssh] for Exec[create /home/vagrant/.ssh/known_hosts]

And the subsequent error about the user.
