Android: Make wpa_cli work on wifi.interface without extra params

Browse source 
Currently wpa_cli connects to global control interface if -i/-p
parameters are not specified. wpa_cli on global control interface
is not useful since the prefix like "IFNAME=wlan0 " needs to be
added to some commands like "IFNAME=wlan0 scan". And, specifying
-i/-p parameters every time is annoying. To improve efficiency of
debugging, this patch enables to make wpa_cli work without extra
parameters.

If you still want to connect to global control interface,
the following command can be used instead:

 $ wpa_cli -g@android:wpa_wlan0 (or -gwlan0)
