Skip flaky CTS tests for presubmit

Skip testRegisterCallbackWithCarrierPrivileges and
testContinuousQueriesInline for presubmit, as they are highly flaky.
These tests are still run in postsubmit as part of MTS. In order to put
the CTS suite in presubmit as early as possible, add the annotation so
they are skipped in TEST_MAPPING.
