Clojure's approx= test function has a weakness

[taliesinb]

Description

The clojure framework's approx= test utility function (defined in contrib/clojure-package/test/org/apache/clojure_mxnet/util_test.clj) is unable to detect differences between arrays if they are of different sizes and the difference occurs in the excess.

For example, this returns true, but should return false:

(approx= 1e-9 [1 1 1] [1 1 1 9 9 9])

This means that tests that use approx= in the clojure test suite can incorrectly succeed.

I have fixed this in #12064.
