[gtk+/wip/otte/shader: 127/269] gskslfunction: Change name printing to name getting

[Benjamin Otte <otte src gnome org>]

commit 5186ef9fc6244650db6b365286d430c8231b66dd

    gskslfunction: Change name printing to name getting
    
    Since gsk_sl_type_get_name() exists now, we can have a name getter also
    for builtin constructors.
