CtsOsTestCases: Test fails due to Text change for Allow in permissions

To grant the permissions, the option with text 'Allow' is clicked in the test cases.
But when the test is changed to as per the customer reqirement the test case fails.
Fix is to find the text using text ID and click the option. Finding the option using text ID is already available.
Reused same to fix the issue.
