guix: emacs-utils: Make emacs-compile-directory forwards-compatible.

Browse Source 
Newer (development) builds of Emacs 30 mark a number of functions related to
native compilation as ‘internal’.  Since we rely on such functions and there
does not appear to be a high-level replacement at the moment, let's work
around this case.

* guix/build/emacs-utils.scm (emacs-compile-directory): Require comp early
and check if ‘comp-write-bytecode-file’ is available.

Fixes: Upstream renamed comp-write-bytecode-file <https://bugs.gnu.org/69201>
