build: Expand ‘scripts/guix’ at Make time.
This moves the complexity of Autotools variable expansion outside of the application code. * scripts/guix.in (config-lookup): Delete. (maybe-augment-load-paths!, run-guix-main): Use fully expanded variables instead of calling ‘config-lookup’. * configure.ac: Don't use AC_CONFIG_FILES for ‘scripts/guix’. Use AC_PROG_SED. * Makefile.am (scripts/guix): New rule. (do_subst): New variable. (CLEANFILES, EXTRA_DIST): Adapt. Co-authored-by: Ludovic Courtès <ludo@gnu.org>
