currently no, none of the races have a racial that makes them better at enchanting.
one of the new BC races does have +15 or so to enchanting, but can't remember which one, it's subject to change, and probably not a good enough reason to choose one race over another.
Or as I like to see it, any race can make it to level 5 and disenchant as well as any other race. :-)
