Don't duplicate event sending code in wxGTK wxListBox.

Browse Source 
Reuse wxListBoxBase::SetEvent() instead of duplicating its code in wxGTK.

Also get rid of the code checking for selection of the item with index -1:
this can't happen any more since r65865 which changed GTK_SELECTION_SINGLE to
GTK_SELECTION_BROWSE.
