BlackBerry Plugin: support 8 mouse buttons, instead of just 3.

Browse Source 
The mask of possible mouse buttons in QNX provides tracking for the
up/down State of up to 8 mouse buttons. This update adds support
for the 5 buttons which we previously ignored in Qt on this Platform.

Task-number: QTBUG-24682
