Please review this test fix.

This test tests the locking of the compilers - make sure no compiles can 
be completed while the lock is in place. When running with 
-XX:-TieredCompilation and -XX:CompileThreshold=100 we got a fairly long 
queue of compiles waiting, and when only C2 is available it can take 
longer to complete than the test wait time.

Only allow compile of the test method - make sure we have no contention 
on the compile queue. With only a single method in the queue we can also 
reduce the wait time.

Test run in failing configuration.
