Node.js FTBFS Fixes

[Stephen Gallagher]

As part of efforts around the Base Runtime, I'm working through several FTBFS
issues in Node.js packages in Fedora 25. Most of these are due to packages that
were built prior to the release of Node.js 6.5, which slightly changed the
semantics of the test runner for expected results.

Most upstreams have a patch for this that works (occasionally with minor
modifications), so I'm just pulling those down where possible and otherwise
disabling the individual tests if not.

I do not plan to issue Bodhi updates for these changes; I only need the builds
in Koji to pull them into the Base Runtime build environment.
