add skip event counter for xkb events

if we are setting the group or the set of groups in e we will receive a
XkbNotifyState Event from x, which will result in a
ECORE_X_EVENT_XKB_STATE_NOTIFY event. We are setting there again our
settings, since we need to reset the settings from a potential external
application. So we should only reset our settings when the event is not
expected by e.
