We previously used `( ... )` subprocess for each init script
to prevent the `exit` command from exiting `rcS/K`.
Instead, define the `EXIT=return` in `rcS/K` and use `${EXIT:-exit}`
in the scripts instead of the `exit` command.
`${EXIT:-exit}` will expand to `exit` if `$EXIT` is not set,
allowing these scripts to be called directly as well.
This only applies to system scripts. We still use subshells
in `S99localscripts.sh` to avoid breaking any user scripts.
