bluetooth: add function to hide Bluetooth settings

We support USB Bluetooth adapters being inserted and removed from our
older Chromebooks, so as well as showing the Bluetooth settings on

adapter is pulled out.

BUG=chromium-os:27103
TEST=(with plumbing from later CL) removed adapter, verified the settings section vanished
