Attachment 77545: Fixed usage of USE_SYSTEM_MALLOC

------- Additional Comments from Konstantin Tokarev <annulen at yandex.ru>
Currently wtf/wtf.pri checks for USE_SYSTEM_MALLOC presence. However
build-webkit script sets USE_SYSTEM_MALLOC=1 if --system-malloc key is
added (compare with, e.g., ENABLE_GLIB_SUPPORT=1).
    
This patch improves consistency of USE_SYSTEM_MALLOC usage across build
system
