devcons: remove cpunote file

the cpunote file is ment to be read by the remote side
to transport interrupt notes from the client side. drawterm's
implementation just blocks forever as we do not handle
9p flushes, it prevents the server side noteproc to
be killed keeping the 9p connection open even after the
remote command exits.
