Fix arity exception msgs for Clojure 1.10, 1.11

[lread]

We were almost taking into account the sci.impl. fn name prefix that
shows up in Clojure 1.10+, but not quite.
Now also only applying arity conversion code to arity exception messages.

We were previously accidentally only testing against Clojure 1.9.0, so
these test failures went unnoticed.

Fixes #791

@borkdude, I'm now curious as to why the native tests worked prior to my fix.
I think the Graal native-image build uses Clojure 1.10.3 so they should have failed?
I'll take a peek tomorrow to answer this question.

Ah. The failing tests are not run under native-image:

sci/test/sci/core_test.cljc

Lines 406 to 407 in 4981762

	(deftest error-location-test
	(when-not tu/native?

This is probably just due to the technically complexity of verifying them under native-image.

If I temporarily enable the tests for native-image they won't pass because they aren't verified correctly, but the behaviour is correct.

Take this test:

sci/test/sci/core_test.cljc

Lines 414 to 419 in 4981762

	(tu/assert-submap {:type :sci/error, :line 1, :column 15,
	:message #"Wrong number of args \(1\) passed to: user/foo"}
	(try (eval* "(defn foo []) (foo 1)")
	(catch #?(:clj clojure.lang.ExceptionInfo :cljs ExceptionInfo) ex
	(let [d (ex-data ex)]
	d))))

Before this PR, :message is generic: Wrong number of args (1) passed to: function of arity 0
After this PR, :message is, as expected, specific: Wrong number of args (1) passed to: user/foo

Thanks!
