It is to be expected since ":exports both" is meant to leave source code
behind.

Anyway, the following works for me (I had to tweak your regexp):

--8<---------------cut here---------------start------------->8---
  #+LATEX_HEADER: \usepackage[right=2in,left=0.5in]{geometry}
  #+LATEX_HEADER: \usepackage{parskip}

  * Setup                                                                 :noexport:
  #+BEGIN_SRC emacs-lisp :exports both
  (defun margin-graphics (contents backend info)
      (when (eq backend 'latex)
        (replace-regexp-in-string "\\`\\\\includegraphics.*?\\({.+}\\)"
  "\\\\marginpar{\\\\includegraphics[width=0.9\\\\marginparwidth]\\1} "
  contents)))

  (add-to-list (make-local-variable 'org-export-filter-link-functions) 'margin-graphics)
  #+END_SRC

  * Document

  [[file:~/Documents/work/2-data/images/2-echantillonnage-1-fluctuations-fig1.png]]
--8<---------------cut here---------------end--------------->8---

I suggest to use `make-local-variable' to keep global filters list
clean.
