[gnome-boxes] Download http directly via libsoup

[Alexander Larsson <alexl src gnome org>]

commit 16cb6ed609ae32a386844d1c32e50e34b07b36c3
Author: Alexander Larsson <alexl redhat com>

    Download http directly via libsoup
    
    The GVfs http support works for this, but is quite overcomplicated for
    pure file downloads. Directly using libsoup means less dependencies
    and more direct codepaths (library calls instead of multiple
    cross-process dbus calls).
