Thanks for applying this.

I didn't notice that Emacs stopped setting ‘scheme-mode’ automatically
due to the extra line implied by the use of the Guile meta switch.

Here is a fix to please Emacs.

Since commit 6f774d481839f87178c5895ac2d661e141f879b8 which introduces the use
of Guile's meta switch in “scripts/guix.in”, Emacs was not using ‘scheme-mode’
for this file.

* scripts/guix.in: Replace "-*- scheme -*-" with a local variable.
