Tighten another spec in core/hash/equal_value_spec.rb
Tighten another spec in core/hash/equal_value_spec.rb

Hash#== compares keys with matching hash codes via eql?

This spec was using hash keys where key.eql?(key) was false.

That's pretty pathological, but there's probably some real
non-conformance with MRI here.  MRI can test for object identity
without calling eql? so a key is still found even if it doesn't
eql? itself.

That's not really related to the behavior this spec is specifying,
though.  So, this patch just uses a less pathological implementation
of eql?
