Accepts fonts that are not to add 0-padding at the final table.

Some fonts automatically generated by a font generator, called TTX, 
seems to not to add 0-padding to the final table so OTS will reject 
these fonts. The table should be 0-padded, but it would be OK to accept 
these fonts. This change makes OTS accept such fonts.
