ipc/sem.c: bugfix for semctl(,,GETZCNT)
GETZCNT is supposed to return the number of threads that wait until a
semaphore value becomes 0.
The current implementation overlooks complex operations that contain
both wait-for-zero operation and operations that alter at least one
semaphore.
The patch fixes that. It's intentionally copy&paste, this will be
cleaned up in the next patch.
