Change sepolicy permissions to now classify hostapd as a HAL exposing
HIDL interface.
Sepolicy denial for accessing /data/vendor/misc/wifi/hostapd:
12-27 23:40:55.913 4952 4952 W hostapd : type=1400 audit(0.0:19): avc:
denied { write } for name="hostapd" dev="sda13" ino=4587601
scontext=u:r:hal_wifi_hostapd_default:s0
tcontext=u:object_r:system_data_file:s0 tclass=dir permissive=0
01-02 19:07:16.938 5791 5791 W hostapd : type=1400 audit(0.0:31): avc:
denied { search } for name="net" dev="sysfs" ino=30521
scontext=u:r:hal_wifi_hostapd_default:s0
tcontext=u:object_r:sysfs_net:s0 tclass=dir permissive=0
Bug: 36646171
