databases from 4.0 server

mysqldump treated a failure to set the results charset as a severe
error.  

Now, don't try to set the charset for the SHOW CREATE TABLE statement,
if remote server's version is earlier than 4.1, which means it 
doesn't support changing charsets.


client/mysqldump.c:
  Don't set the charset for receiving results if the server doesn't 
  support it.
