eo - fix - fix alignment of eo object class structs - it was wrong 

the alignbment logic was wrong. we have to use the worst case. that
means 8 or 16 byte alignment. eina mempool alignment logic is wrong
for this as it assumes an array of typoes of all the same size...

this fixes crashes seen on armv7 with sigbus in new gesture code which
got unlucky.
