[Libguestfs] [PATCH 2/3] v2v: -o rhv-upload: Only set SSL context for https connections.

[Richard W.M. Jones]

For real imageio servers the destination will always be https.  This
change has no effect there.

However when testing we want to use an http server for simplicity.  As
there is no cafile in this case the call to
ssl.create_default_context().load_verify_locations(cafile=...) will fail.
