[glib: 1/2] The ETag returned by various GFile functions is nullable

[Philip Withnall <pwithnall src gnome org>]

commit b41147dfc9a993dd6af4c165c88135fd2da98190

    The ETag returned by various GFile functions is nullable
    
    This was correctly annotated for proper return values but in case of out
    parameters it was only annotated as (optional) and not additionally as
    (nullable).
