[libvirt] [PATCH v2 3/3] qemu: Generate channel target paths on hotplug as well

Since commit 714080791778e3dfbd484ccb3953bffd820b8ba9, qemu agent channel cannot be plugged in because we won't generate its path automatically. Let's not only fix that, but also add tests for it so next time it's checked for.
