    rc.d/ddb: Really silently exit
    
    The comment says “silently exit if ddb is not enabled”, but we'd exit
    with an error message.
    
    Note that I switched the sysctl variable used to test for the presence
    of ddb from debug.ddb.scripting.scripts to d.d.s.script, which has a
    smaller value if set.
    
    While here, drop a pointless fork-exec, and use ${SYSCTL_N} for
    consistency.
