Fix 'bodhi updates new' command parameters
    
    Command given in Multi-package builds section did not work.
    Changed to use parameters that actually work,
    and do what the previous form was intended to do.
    
    Note that the command does not take 'user' as input at all.
    Probably it is using Kerberos authentication,
    so that the user has already been set when 'fkinit' was called.
