[recipes] Prepopulate user data from system

[Matthias Clasen <matthiasc src gnome org>]

commit bd14392ef0d2f5bd961961a00e6368026103a9a4
Author: Matthias Clasen <mclasen redhat com>

    Prepopulate user data from system
    
    If we don't have the user id stored yet, fall back to user
    the Unix account data. Once we have an account information portal,
    we can include a user photo in here too.
    
    This should fix ebassi's problem where he couldn't edit his user
    data because there was a chef ebassi in the shipped database.
