always exit from cleanup

There's no use case for us calling cleanup without exiting afterwards,
so we can simplify all of our cleanup;exit; calls into just cleanup.
This means our sighandler is no longer needed (it wasn't really, to
begin with), but we split it up to make sure we exit with a posix-ish
128+signum exit value.
