[Fix #2163] Disable native compilation in emacs-lisp checker
The byte-compile subprocess exists only to collect warnings, but with
native compilation enabled it also emitted .eln files into the user's
native-comp cache (respecting native-comp-eln-load-path was the original
request). Set no-native-compile so the side effect is gone entirely,
which also skips wasted compilation work.
