[bug#67260] [PATCH v8 5/7] build-system: emacs: Compute relative file names.

[Liliana Marie Prikler]

With the previous commit, relative file names are expanded relative to
ELN_DIR -- more or less.  To make use of this in emacs-build-system, we must
also pass relative file names.

* guix/build/emacs-build-system.scm (emacs-compile-directory): Compute the
relative file names of the files to compile.
