This code is much more sophisticated in that it doesn't rely on argv[0], but rather asks the OS where our executable is. We can then simply go two steps up since we count on running in out/Whatever relative to the src dir. This is how Chromium does it. The aim here is to get rid of SetExecutablePath, which will be the next CL.
