emacsWithPackages: do not add the wrapper path twice

"$out/share/emacs/site-lisp" is added to load-path in wrapper.sh[1]
using EMACSLOADPATH and "$out/share/emacs/native-lisp/" is added to
native-comp-eln-load-path in wrapper.sh[2] using
EMACSNATIVELOADPATH. There is no point to add them again here.

Additionally, the trailing "/" in "$out/share/emacs/native-lisp/"
causes duplicate entries in native-comp-eln-load-path:

("/nix/store/hash1-emacs-packages-deps/share/emacs/native-lisp/" ; [3]
 "/home/user/.emacs.d/eln-cache/"
 "/nix/store/hash1-emacs-packages-deps/share/emacs/native-lisp"  ; [2]
 "/nix/store/hash2-emacs-29.1-rc1/lib/emacs/29.1/native-lisp/")

load-path does not change with this patch applied.
