kernel.c: regression on struct/array/hash == override with super; fix #6660

Browse Source 
when overriding struct#==, array#==, or hash#== with super, the recursion
detection incorrectly treated the super call as a circular reference. this
was caused by commit 5ca2d442 which added recursion detection.

the fix introduces mrb_recursive_func_p that starts from ci[-2] instead of
ci[-1], skipping the immediate parent frame which may be a ruby override
calling super. equality methods (==, eql?) now use this function, while
inspect methods keep using mrb_recursive_method_p for immediate circular
reference detection.
