gnu: emacs: Wrap EMACSLOADPATH.
With this, the search path specification of EMACSLOADPATH does no longer
depend on the version of Emacs, which should make upgrading major versions
less painful. See also:
- <https://bugs.gnu.org/43627>
- <https://bugs.gnu.org/47458>
* gnu/packages/emacs.scm (emacs)[#:phases]: Add ‘wrap-load-path’.
[native-search-path]<EMACSLOADPATH>: Do not search for builtin libraries.
(emacs-next)[native-search-path]: Inherit from emacs.
