[11] RFR JDK-8198653: ClassLoader::getSystemClassLoader throws InternalError when called after shutdown

[mandy chung]

JDK-8198249 added a new shutdown VM initLevel.  ClassLoader::getSystemClassLoader
should be updated to handle the new case.  I checked all other callers of
VM::initLevel and no other place needs update.

Thanks
Mandy
