etc/rc.d/wpa_supplicant: Fix broken check for ndis(4) interfaces.

With the new wlan stack, we need to check a sysctl to determine if it
is an ndis(4) interface because it is now wlanX that gets passed to
the script.

Depending on this, wpa_supplicant(8) will be started with either
"-D bsd" or "-D ndis".
