Bug 1451519 Convert specialpowers to a webextension r=kmag

This is a quick-and-dirty port.  It might be nice to replace
SpecialPowersObserver with the webextensions content script injection
system at some point, but that isn't practical right now (since WE experiments
cannot implement new APIs visible to content scripts).
