Documentation/SubmitChecklist: add RCU debug config options

There have been persistent lockdep RCU splats, indicating that submitters
are not testing with CONFIG_PROVE_RCU.  Add this config option to the list
in Documentation/SubmitChecklist.  Also add CONFIG_DEBUG_OBJECTS_RCU_HEAD
for good measure.
