[Libvir] [PATCH] Add support for virConnectGetHostname and virConnectGetURI for qemu

Specifically this just adds support for virConnectGetHostname on qemu:/// URIs. Because of the way that the qemu driver now works, calls to virConnectGetURI are answered by the remote driver before the qemu driver ever sees them, so they have worked all along.
