1. Use set instead of vector. This simplifies the code a bit.
2. Use proper NDK constants and functions to check the device
   OS version.

While this does not capture all nuances of optional programs,
go devices, etc. it should be a useful starting point to tell us

* changes:

  Refactor NsdManagerTest

Also add BLUETOOTH_CONNECT permission which is needed for access
PanService if target sdk 31+. The permission would be granted to
privilege application without prompt.

Also remove the min_sdk_version 29 from AndroidManifest because it is
useless that the Android.bp already define min_sdk_version 30.
