Check qtaguid support before private stats test

Browse Source 
The AccessPrivateDataTest and CreatePrivateDataTest is directly testing
the proc file of xt_qtaguid module. These two test will no longer valid
after we block the access from untrusted app to qtaguid proc file. So
remove the AccessPrivateDataTest and added a new qtaguid test to make
sure apps with SDK 28 or above cannot access qtaguid proc file.

Bug: 30950746
Bug: 68774956
Test: run cts -m CtsAppSecurityHostTestCases \
	-t android.appsecurity.cts.AppSecurityTests
