docs: UML: Mention telnetd for port channel 



It is not obvious from the documentation that using the "port" channel
for the console requires telnetd to be installed (see port_connection()
in arch/um/drivers/port_user.c).  Mention this, and the fact that UML
will not boot until a client connects.

* The port channel - start a telnet server on TCP port number. Example:

  ``con1=port:4321``.  The host must have /usr/sbin/in.telnetd (usually part of
