rc.shutdown: print a newline before watchdog timeout message

Previously the watchdog timeout message was appended to the last entry
in the "Waiting for PIDS" list, resulting in a message like

    Waiting for PIDS: 31299 31296 90201 9020090 second watchdog timeout
    expired. Shutdown terminated.

Print a newline to separate the watchdog timeout message.  Also perform
the kill before logging or echoing the message.
