libqos: Use explicit QTestState for remaining libqos operations

Drop one more client of global_qtest by teaching all remaining
libqos stragglers to pass in an explicit QTestState.  Change the
setting of global_qtest from being implicit in libqos' call to
qtest_start() to instead be explicit in all clients that are
still relying on global_qtest.

Note that qmp_execute() can be greatly simplified in the process,
and that we also get rid of interpolation of a JSON string into a
temporary variable when qtest_qmp() can do it more reliably.
