Move the diagnostic output when the rc.subr(8) glue automatically starts a
service behind $rc_quiet. Instead, output a warning if the pre-command
routine or the command itself failed. Arguably, it's more useful to know when
a command failed to start than it is to have an endless list of
"Starting ...." lines[1].

[1] - This change actually helped me to discover a bug in rc.d/{lockd,statd}

(fixed in r179941) that used to fail silently before.
