Drop one more client of global_qtest by teaching all fw_cfg test functionality (invoked through alloc-pc) to pass in an explicit QTestState, adjusting all callers. In particular, fw_cfg-test had to reorder things to create the test state prior to creating the fw_cfg (and drop a pointless strdup in the meantime), but that test now no longer depends on global_qtest.
