compiler/c1/TestTraceLinearScanLevel.java occasionally times out with -Xcomp

compiler/c1/TestTraceLinearScanLevel is occasionally timing out on macosx-x64 when running with -Xcomp.

The test's purpose is to sanity check the TraceLinearScanLevel flag with a hello world like test. It runs with -XX:TestTraceLinearScanLevel=4 which prints quite a lot of data. It becomes even more when running with -Xcomp. Since we only want to sanity check, there is not much benefit in running this test with -Xcomp which only unnecessarily increases the time to run this test.

I suggest to exclude this test with -Xcomp but instead add -Xbatch to at least wait until all the C2 compilations are finished in the start-up.
