    libexec/rc: improve performance of pccard_ether script

    Replace "ifconfig -ul" with "ifconfig -n" because netlink-enabled
    /sbin/ifconfig utility has sub-optimal performance for listing.

    Combined with the commit b1b17432aa1be670564161232d110461a5dde4ce,
    these changes mostly eliminate performance regression of the command
    "service devd start" for a system having hundreds of network interfaces
    created before devd starts, after FreeBSD 14+ switched
    /sbin/ifconfig to netlink(4)
