Issue clarified up-thread:

Generally, assigning the environment variable EDITOR works
for visudo(*), but it appears /usr/bin/vi is hard-coded in
guix's visudo as it does not acknowledge EDITOR.

$ EDITOR=vim visudo ~/etc/guix/sudoers
visudo: no editor found (editor path = /usr/bin/vi)

David Larsson suggested using SUDO_EDITOR, however that
doesn't work either:

$ SUDO_EDITOR=vim visudo ~/etc/guix/sudoers
visudo: no editor found (editor path = /usr/bin/vi)

I'll still use visudo to check my local sudoers file on
the command line, though it's more challenging to remember
to check it (and the consequences of borking sudoers are
severe).

$ visudo --check -f ~/etc/guix/sudoers
~/etc/guix/sudoers: parsed OK

I'm guessing /usr/bin/vi has been hard coded into visudo
for security reasons, but it doesn't make sense if the
/usr/bin/vi editor doesn't exist on Guix System.
