[gvfs/gnome-3-14] http: Report correct size for partial content msg

[Ondrej Holy <oholy src gnome org>]

commit 643498c51747d2b0ff2290352afdac97a9771e02

    http: Report correct size for partial content msg
    
    Content length is wrongly used as file size for partial content
    messages (e.g. after seek), therefor length from range header has
    to be used instead.
