build: Cleanup some path-munging code.
I was looking at this today, and this seems better than the pre-existing code,
generally pre-pending to these paths isn't great...

Include missing dependency requirements
Running `servo-tidy` in a virtualenv where all you've done is `pip install servo-tidy==0.3.0` doesn't actually work because of missing dependencies. PyYAML and voluptuous are required as well. I don't know anything about python package management but declaring these missing dependencies seems like an appropriate thing to do. Patch itself is untested because I don't know how, although with these dependencies installed in my virtualenv running `servo-tidy` works.

Add optional ANGLE support to glutin port
Supporting ANGLE in Servo has two important benefits:
* we can actually run Servo instances on our Windows CI machines, which gives us more confidence that we're not breaking it
* we can continue to use OpenGL on devices like the Hololens, rather than creating platform-specific graphical backends
