Upgrade to tar v3

Tar version 3 performs better and is more well tested than its
predecessor.  npm will be using this in the near future, so there is no
benefit in shipping a node-gyp that uses the slower and less reliable
fstream-based tar.

This drops support for node 0.x, and thus should be considered a
breaking semver-major change.
