sepolicy(hostapd): Add a HIDL interface for hostapd
* Note on cherry-pick: Some of the dependent changes are not in AOSP.
In order to keep hostapd running correctly in AOSP, I've modified this
change to only include policy additions.
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
Test: Device boots up and able to turn on SoftAp.
