Restore the ability to do one-shot upgrades from the versions of npm
bundled with Node 0.8 to npm@3, which simplifies using Travis with old
Node and new npm, for compatibility testing purposes. Older versions of
npm repack packages on install, which works poorly with the way npm@3
handles bundledDependencies with flat trees.
