This doesnʼt really have anything to do with the portable dumper. When
dumping the portion of emacs lisp that you can use is fairly limited,
so you canʼt just go loading seq.el. Try something along the lines of
(untested):

(setq exec-path (delete nil
                 (mapcar
                  (lambda (elt)
                    (unless (string-match-p "Homebrew/shims" elt) elt))
                  exec-path)))

I donʼt think you need to do anything with PATH, Emacs doesnʼt store
that anywhere.
