Improve wrong-arity linter slightly

[jafingerhut]

Right now t.a(.j) libs always use :arglists of a function to check whether there is a call with incorrect arity.

In very recent work on Eastwood I have added a filter that suppresses such warnings if the call has an allowed number of args according to a different set of arglists in Eastwood's configuration.

That is good for suppressing wrong warnings, but it is bad in that it will never catch some calls with wrong arities, because they have allowed arities according to the :arglists contents. It would be best if t.a(.j) used the same arglists that Eastwood does elsewhere.

[jafingerhut]

Perhaps more appropriate would be for Eastwood to ignore the :maybe-arity-mismatch key in the ASTs produced by t.a(.j), and implement its own independent check for all :op :invoke ASTs.
