hostapd: Android: Force group access to ctrl_iface directory

Browse source 
Same fix as d49ea68284 in
wpa_supplicant.

From original commit:

wpa_supplicant is started from /init.*.rc on Android and that seems
to be using umask 0077 which would leave the control interface
directory without group access. This breaks things since Wi-Fi
framework assumes that this directory can be accessed by other
applications in the wifi group. Fix this by adding group access even
if umask value would prevent this.
