fix: name threads on vxWorks

VxWorks task names are limited in length. pthread_setname_np() returns
ERANGE for names longer than the limit and leaves the task unnamed. The
default Qt thread name is the long QObject class name, so threads showed
up unnamed. Qt 5.15 truncated the name; restore that behaviour.

Fixes: QTBUG-148255
