Auto merge of #11646 - pcwalton:real-info-plist, r=metajack

servo: Add an `Info.plist` on the Mac and opt into integrated graphics.

Discrete GPUs cause power use problems and tend to perform badly
with WebRender.

See:

* https://developer.apple.com/library/mac/qa/qa1734/_index.html

* https://reverse.put.as/2013/05/28/gimmedebugah-how-to-embedded-a-info-plist-into-arbitrary-binaries/
