Skip FocusIn events with mode == NOTIFY_MODE_GRAB or NOTIFY_MODE_UNGRAB

According to the Xlib Programming Manual section 10.7.2 [1], these events are
generated when keyboard grabs activate/deactivate, while we are only interested
in focus changes which are done by other programs independend from the
keyboard.
