tst_QHostInfo: fix mem-leaks in threadSafetyAsynchronousAPI() 

Allocate participating threads and objects on the stack, not the heap.

As a drive-by, port from QList to C arrays (never use a
dynamically-sized container for statically-sized data™).

Code predates the public history, all active branches are affected.

Pick-to: 6.6 6.5 6.2 5.15
