econet: remove ancient bug ridden protocol

More spring cleaning!

The ancient Econet protocol should go. Most of the bug fixes in recent
years have been fixing security vulnerabilities. The hardware hasn't
been made since the 90s, it is only interesting as an archeological curiosity.

For the truly curious, or insomniac, go read up on it.

-	  Econet is a fairly old and slow networking protocol mainly used by
-	  Acorn computers to access file and print servers. It uses native
-	  Econet network cards. AUN is an implementation of the higher level
-	  parts of Econet that runs over ordinary Ethernet connections, on

-	  Internet protocol IP.
-
-	  If you say Y here, you can choose with the next two options whether
-	  to send Econet/AUN traffic over a UDP Ethernet connection or over
-	  a native Econet network card.
-
-	  To compile this driver as a module, choose M here: the module
-	  will be called econet.
