[rygel] core: Use libsoup in ImportResource

commit 3bc139e4e6de8cc707cc538527c3a1e1bd4eca0a
Author: Jens Georg <mail jensge org>

    core: Use libsoup in ImportResource
    
    Using GIO has two problems: it needs the external http gvfs module
    which might not be available everywhere and even if it's available,
    the copy operation does a HEAD request first which makes the
    certification test fail.
    
    Partially fixes UPnP CTT testcases AV-CD:1-9.1, AV-CD:1-11.1 and
    AV-CD:1-12.1
