ui: convert VNC startup code to use SocketAddress
The VNC code is currently using QemuOpts to configure the sockets connections / listeners it needs. Convert it to use SocketAddress to bring it in line with modern QAPI based code elsewhere in QEMU. Reviewed-by: Eric Blake <eblake@redhat.com> Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
