Whitelist vendor-init-settable bluetooth_prop and wifi_prop

Values of the following properties are set by SoC vendors on some
devices including Pixels.
- persist.bluetooth.a2dp_offload.cap
- persist.bluetooth.a2dp_offload.enable
- persist.vendor.bluetooth.a2dp_offload.enable
- ro.bt.bdaddr_path
- wlan.driver.status

So they should be whitelisted for compatibility.

Test: succeeded building and tested with Pixels
