netconsole.txt: revision of examples for the receiver of kernel messages

There are at least 4 implementations of netcat with the BSD-based
being the only one that has to be used without the -p switch to
specify the listening port.

Jan Engelhardt suggested to add an example for socat(1).

initialized and attempts to bring up the supplied dev at the supplied
address.
The remote host can run either 'netcat -u -l -p <port>',
'nc -l -u <port>' or syslogd.
The remote host has several options to receive the kernel messages,
for example:
1) syslogd
2) netcat
On distributions using a BSD-based netcat version (e.g. Fedora,
openSUSE and Ubuntu) the listening port must be specified without

'nc -u -l -p <port>' / 'nc -u -l <port>' or
'netcat -u -l -p <port>' / 'netcat -u -l <port>'
3) socat
