Without this, installing the twrp app as system app leads to
reboot loops into recovery with log messages like:
java.lang.IllegalStateException: Signature|privileged permissions not in privapp-permissions whitelist: {me.twrp.twrpapp: android.permission.READ_PRECISE_PHONE_STATE, me.twrp.twrpapp: android.permission.BATTERY_STATS, me.twrp.twrpapp: android.permission.PACKAGE_USAGE_STATS}
