Subject: conf: Add USB redirect devices to domain capabilities

As qemu becomes more modularized, it is important for libvirt to advertise
availability of the modularized functionality through capabilities. This
change adds USB redirect devices to domain capabilities, allowing clients
such as virt-install to avoid using redirdev devices when not supported
by the target qemu.
