In particular, don't add trailing backslashes introduced by `xautolockExtraOptions`. Systemd's unit file parser seems to have gotten a bit stricter and with systemd 242, the trailing backslash caused the next non-empty line to be ignored. In that case, this was `[Section]`, so all subsequent settings were mistakenly added to `[Service]`, causing them to be ignored entirely. Simplify and fix this by using `concatStringsSep` to build a single `ExecStart` line.
