Ruby: changing deprecated rb_cData to rb_cObject.
Ruby 3.0 deprecated rb_cData with the intention to remove it in release 3.1. This commit changes references of rb_cData to rb_cObject. This was done so we can support distributions that package Ruby 3.0, such as Fedora 34. We also need to call rb_undef_alloc_func because we're no longer deriving from rb_cData. This prevents unnecessary allocations. See: https://docs.ruby-lang.org/en/3.0.0/doc/extension_rdoc.html "It is recommended that klass derives from a special class called Data (rb_cData) but not from Object or other ordinal classes. If it doesn't, you have to call rb_undef_alloc_func(klass)."
