Bluetooth: make LE-only devices add "LE:" as an address prefix

This seems a bit odd, but it actually has three different reasons for it:

 - It's a visual indication of BT LE mode for users

 - the rfcomm code only works with legacy BT support, and if we scan a
   device that only does LE, we want the custom serial code to instead
   automatically fall back on a "emulate serial over LE packets" model.

 - we want rfcomm to remain the default for devices that do both legacy
   BT _and_ LE, but we want people to have the ability to override the
   choice manually.  They can now do so by just editing the address
   field and adding the "LE:" prefix manually, and it automatically gets
   saved for next time.

So while a bit hacky, it's actually a very convenient model that not
only works automatically, but allows the manual override.
