Set CONFIG_NO_RANDOM_POOL=y
Wpa_supplicant's random pool is not necessary on Android. Randomness
is already provided by the entropymixer service which ensures
sufficient entropy is maintained across reboots. Commit b410eb1913
'Initialize /dev/urandom earlier in boot' seeds /dev/urandom with
that entropy before either wpa_supplicant or hostapd are run.
Bug: 69962344
Test: Connect to access point using WPA2 with password.
Test: Enable Wifi tethering. Tether Marlin to Taimen.
