MAINTAINERS: add virtio-* tests

Except virtio-9p, all virtio-* tests are orphan. This patch tries to fix
it, according to the following logic:

- when the related subsystem has its own section in MAINTAINERS, the test
  is added there
- otherwise it is added to the "parent" section (aka. SCSI, Network devices,
  virtio)
