dir-locals.el: update emacs config to match meson style

The config is copied from systemd. The existing config specified 4-space
indent for C, but individual files override this and the files in fact use
8 spaces.

The config for Python doesn't seem necessary anymore either. I think utf-8
is used everywhere by default.
