gnu: Add emacs-next.
Add `emacs-next' for building latest Emacs from git. * gnu/packages/emacs.scm (emacs-next): New variable. (emacs): make the autoload deletion snippet not fail when eshell/esh-groups.el does not exist. This enables reuse of the entire snippet field of `emacs' for `emacs-next'. * gnu/packages/patches/emacs27-exec-path.patch: New file. * gnu/local.mk (dist_patch_DATA): Add the above patch file to it. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
