Eric Blake 05e520f1c7 libqos: Use explicit QTestState for fw_cfg operations
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.
