fix(cli): site file loader

I had missed the fact that -Q implies not only
--no-site-file (intended), but --no-site-lisp (unintended). Without the
latter, no site-lisp directory is left in load-path, and any attempt to
load it after-the-fact (which I do in core-cli.el) will fail. Thanks to
@yamanq for noticing this!
