[gnome-initial-setup/wip/feborges/generate-user-pics: 2/3] account: Make the user picture button transparent

[Felipe Borges <felipeborges src gnome org>]

commit ece278223c9dc97969ac18de54dc6bac99a48410
Author: Felipe Borges <felipeborges gnome org>

    account: Make the user picture button transparent
    
    Since the generated pictures are rounded, it looks quite ugly to
    have a squared button in there.
    
    This is compatible with the mockups for the Settings User Panel[0].

    Fixes #6
