When emergency_shell() happens, it does 'setsid --help' to figure out if
the setsid binary supports the '-c' flag (to set the controlling tty).
This output shows up in the logs (and on-screen if you're using
rd.debug), which keeps confusing people looking for other problems.
Using "case" instead of "strstr" lets us avoid this.
