windows: Handle the case where there are no serial ports at all.

It's possible for the HARDWARE\DEVICEMAP\SERIALCOMM key to not exist in
the registry if there are no serial ports at all and never have been, as
discovered on my rather minimalist gaming machine.

Handle that case gracefully and return an empty list.
