Don't expose Array.prototype.values as it breaks webcompat

Don't expose Array.prototype.values as it breaks webcompat

Some versions of Outlook Web Access test for the existence of a 'values'
property on Array instances, so adding the 'values' iterator to the prototype
(even with @@unscopeables) causes breakage.

This matches Gecko: they ship Array.prototype.{keys,entries} but not 'values'.
