keyboard: change the function to use

QMap::take(const Key &key) is more efficient.
Short description for take():
  "Removes the item with the key from the map
   and returns the value associated with it."
For more information, see 'http://doc.qt.io/qt-5/qmap.html#take'.
And the value function is a constant function.
