Update tulip net driver to indicate link beat to system,

via netif_carrier_{on,off}.  Some placeholders to do this were
already in the code, making this an even easier and more obvious patch.

Also, decrease time until next link beat check, if link beat
is not present.  (previously the code would wait 60 seconds until
next check, regardless of current link state)

* 21142.c (t21142_timer): Use return value of
tulip_check_duplex() to indicate to system whether or not
carrier is present. Use carrier presence/absence to determine
when next the 21142 media timer should check for link beat.
* timer (tulip_timer): Un-comment-out calls to
netif_carrier_{on,off}, as there is now value in
reporting link beta information to userspace.
