Use nockmaEq instead of Eq instance to detect nil terminator (#3149)

`unfoldList` should work with for lists like:

* `[5 0]`
* `[5 nil]`
* `[5 tag@myNilTag 0]`
* etc.

currently `unfoldList` will work only for list `nil` terminators that
are tagged with `unfoldList`. `nockmaEq` compares nock terms ignoring
debug annotations, so the above lists will work correctly.
