QGestureManager: port Q_FOREACH to ranged-for [3/6]

The "conflictedGestures" QHash is local to the function, and the code in
the loop body doesn't change it. The "gestures" QList (the value in the
QHash key/value pair) isn't changed in the loop (both the enclosing
for-loop and the for-loop iterating over the QList itself):
- the QGestureEvent constructor takes by const& so it couldn't have
  changed the QList

So use a const QList& instead of a copy.
