Loosen the SDK requirement of a test case in OdRefreshTest. OdRefreshTest.CompileSetsCompilerFilterForSystemServer has a check that skips the test case when the SDK version is lower then 31. However, Android S (SDK level 31) has not been pushed to AOSP, causing the test to be skipped on AOSP. This change lowers the min SDK version to 30.
