Run testExcludedRoutesDisabled only in APKs with target SDK < T.

This test crashes if run from an APK that has target SDK 33 or
above because it tries to disable a compat change that on those
SDK versions is enabled by default.

Run it only in CtsNetTestCasesMaxTargetSdk31 and skip it in our
regular CTS modules.
