Improve the dhcp handling of pccard_ether.

There are now many configurations which have a NIC on board and
cardbus slots too. If a dhclient was already running on the internal
NIC, the user was forced to kill a running dhclient manually.

If now a pccard is included at startup time, /etc/rc.d/dhclient
start does include it into the startup list for dhcp devices.
That means you can now do dhcp on the internal and the pccard devices
at the same time. If the card is plugged in later, a running dhclient
(working for the internal interface only) is killed, and restarted,
but the interface name of the new pccard is added to the internal
name. After removal, /etc/rc.d/dhclient is started again. This
script does nothing if there are no devices in /etc/rc.conf

This is only a workaround for a well known problem. After we have
a dhcp client which handles device adding and removal, it will go
away.
