Check kernel version before running qtaguid test

Browse Source 
The qtaguid module is required for devices running kernel earlier then
4.9, but is no longer avaliable after that. Add a check before running
the kernel qtaguid native test so it doesn't fail on new devices.

Bug: 30950746
Test: run cts -m CtsNativeNetTestCases
