This reverts commit a7db92d9b389cbe565395523882c34c6eff2c21a, this time with
the more careful command, to avoid a world rebuild:

grep -rl --exclude-dir=build --exclude-dir=patches --exclude=ld-wrapper.in \
  --exclude=sitecustomize.py --exclude=guix-emacs.el maxim.cournoyer@gmail.com |
  xargs sed -i 's/maxim.cournoyer@gmail.com/maxim@guixotic.coop/g'

variable to 19.

This is a follow-up to 8f8ec56052766aa5105d672b77ad9eaca5c1ab3c, which only
covers building initrd, while the booting code still tries to load nonexistent
files for builtin modules.

nonexistent module files.
