Refactor RFCOMM / BluetoothSocket usage of LocalSocket

LocalSocket is used by BluetoothSocket. BluetoothSocket
passes a pre-created file descriptor to LocalSocket that
is then given to the LocalSocketImpl.

Commit b08c7bc0bdc48ae95be2697ca27ea89a9dd92c3e broke the
behavior. Commit 7a8c36aa4e6a1b5e48f0ee5a787f10bcfece7587
put in a minimal fix.

This change tidies up LocalSocket and associated classes
and replaces a specialist constructor with a factory method
to highlight the special case. While there an unnecessary
exception has been removed.
