nit: don't need the explicits.

Welcome to C++11!

I'll un-explicit them for consistency, but I half feel like we should just
explicit all of our constructors for ease of review and future-proofing against
uniform initialization (even if we will likely not ever have it in Chromium).

Oh cool! Sorry, I'd assumed this was an oversight and was reviewing on
autopilot. Uniform initialization looks neat.
