Explicitly start adb server

Summary: We were relying on adbkit to do this, implicitly by calling listDevices(). However, this doesn't appear to be reliable, with retries, it usually succeeds, but sometimes still doesn't. I'm aiming to avoid all this entirely by just starting it directly using adb itself, which I expect to be much more reliable.
