INTEGRITY: Prevent deletion of virtual functions

Browse Source 
In release builds -olink also enables deletion of (unused) virtual
functions. In some cases this can lead to application crashes when
using loaders combined with timers. Prevent this by adding
-no_uvfd option to release build flags.

Task-number: QTBUG-99506
Pick-to: 6.3 6.2 5.15
