958ac278cd qemumonitorjsontest: AddNetdev: Use real variant
QEMU now formalized the arguments of netdev-add in the schema, so we
must use a real type to pass the schema validation once the schema is
updated.

The 'user' variant doesn't have any other mandatory fields.

The DO_TEST() macro in qemumonitorjsontest.c was not passing the

In the process of mechanically altering tests to pass the schema

next patch will do some further cleanups that it exposes.

Tested by using this hack, where the test mistakenly passed pre-patch,
but correctly diagnosed the garbage post-patch:
