    um-utils: consider "shared" username to be in use
    
    At the point that we generate possible usernames to go with a user's
    full name (and, in our case, silently choose the first one) the "shared"
    user does not yet exist. But if the user enters their full name as
    "shared", we should not generate the username "shared" as a candidate.
    (In this case, the generated username will now be "user" – not ideal,
    but tolerable.)
    
    (The alternative would be to not try to create the normal "shared" user
    in this case, or use a different name. However, username "shared" has
    special handling in GDM on Endless, to clear various bits of state when
    their session begins and ends.)
