tools: make --quiet actually suppress output

When calling daemon_stop() with --quiet and e.g. the pidfile is empty,
it won't return early since while "$fail" is set, "$2" is "--quiet", so
the if condition isn't met and it will continue executing, resulting
in error messages in the log:

> Sep 14 14:48:33 localhost watchfrr[2085]: [YFT0P-5Q5YX] Forked background command [pid 2086]: /usr/lib/frr/watchfrr.sh restart all
> Sep 14 14:48:33 localhost frrinit.sh[2075]: /usr/lib/frr/frrcommon.sh: line 216: kill: `': not a pid or valid job spec
> Sep 14 14:48:33 localhost frrinit.sh[2075]: /usr/lib/frr/frrcommon.sh: line 216: kill: `': not a pid or valid job spec
> Sep 14 14:48:33 localhost frrinit.sh[2075]: /usr/lib/frr/frrcommon.sh: line 216: kill: `': not a pid or valid job spec

Fix this by moving the --quiet check into the block to log_failure_msg(),
and also add the check to all other invocations of log_*_msg() to make
--quiet properly suppress output.
