check: exit with exit code 1 after printing the usage message

If check is passed an invalid command line option, exit with a
non-zero exit code so that a script calling check can detect the
failure.  The check script already performs an "exit 1" if a valid
option has an invalid argument, so this is consistent with existing
practice.
