node 0.10.34

Version bump, and merging in some of the changes from #33017.
I killed this because it was consistently failing the bot, but we already essentially test npm in principle by making it install the [latest version here](https://github.com/Homebrew/homebrew/pull/33524/files#diff-ba7ac8bf3cbc78ff35d6909b6074ee5eR61). It's not overly desirable, but if we keep on top of npm releases we should see any failures happening in the install stage rather than the testing stage, making this little line here semi-redundant.
