WUtil: make sure wmalloc/wrealloc won't fail because of abort handler

Browse Source 
As pointed by Coverity (#50074), despite the expected behaviour that
'wmalloc' should never return NULL, it may still happen if an abort handler
set by user (with wsetabort) does not call exit() as expected. In such
case we call exit ourself to be sure not to return NULL.
