Adding support to update already defined event's attribute with event modifier. This change will allow to use group modifier as an update to the existing event modifiers. Adding 'add' parameter to the parse_events__modifier_event function. Calling it with 'add' = false/true, the event modifier is initialized/updated respectively. Added exclude_GH flag to evsel struct, because we need to remember if one of 'GH' modifiers was used for event. The reason is that the default settings for exclude_guest is 1 and during the group modifier processing we have no other way of knowing if it was set by default or by event modifier. Keeping the current behaviour, that any event/group modifier reset the defaults for exclude_host (0) and exclude_guest (1).
