punycode: update to 1.4.1

Update punycode to the latest released version. This is mainly in
order to further reduce the maintenance burden. In
nodejs#1246 a fix introducing `new` to
errors was introduced and it has since been ported back to the
punycode library.

This puts Node back in sync with the library itself so it can receive
future fixes and updates directly.
