Subject: bug#61707: Remove function-alias-p NOERROR argument

`function-alias-p` is new in Emacs 29, and takes an optional NOERROR argument which has become entirely useless in Emacs 30 where it is only present for compatibility.

Given that the NOERROR argument is not very useful in Emacs 29 either, what about removing it in that version as well? After all, rather silly to introduce something that's known to go away the next release.

Proposed patch attached.
