emacs-29 d4fc701297: Tolerate missing elpa-packages.eld files

commit d4fc70129786f0c90f76e1868203d63a59f3f92d

    Tolerate missing elpa-packages.eld files
    
    * lisp/emacs-lisp/package-vc.el
    (package-vc--download-and-read-archives): Replace
    'condition-case-unless-debug' with a regular 'condition-case'.
    
    It appears a few people using third-party archives that don't serve
    package specifications have been having issues with package-vc, when
    toggle-on-error is enabled.  In their case, package-vc would raise an
    error in its first invocation, but it would go on working normally
    afterwards.  As this behaviour is confusing and the user can't do much
    about a missing elpa-packages.eld to begin with, we satisfy ourselves
    with printing out a message and continuing on.
