When running without all the subsystem events enabled in nOS-V, it is possible to emit two consecutive VTx events, which would push twice the same value ST_TASK_BODY into the subsystem channel. This change relaxes the subsystem channel to accept duplicate stacked values. A regression test is also added. Reported-By: Raúl Peñacoba Veigas <raul.penacoba@bsc.es>
