package/wpa_supplicant: adding ifupdown support

Browse Source 
Actually, configuring a wifi interface as per "interfaces" man:

auto wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant.conf

doesn't work on buildroot because the line wpa-conf is ignored due to
the lack of a proper ifupdown script to handle the wpa_supplicant
initialization.
