JDK-8149925 causes InnocuousThread be created early during startup before the system class loader is initialized.  Since the common Cleaner is intended for system cleaning code to use, this patch now creates InnocuousThread with null TCCL and expects the system cleaning code to handle null TCCL only if it uses it.
This looks okay although the hasTCCL flag is a bit ugly. An alternative 
would be for InnocuousThread to take the TCCL in the constructor and 
have it reject all but null or the SCL.
