cupsd arguments don't allow retrieval of information about reason for termination

[Karl-Philipp Richter]

Invoking `/usr/sbin/cupsd -f` simply prints ~`Terminated`[1]. Assuming there's no output about the reason at all (i.e. neither to stdout or stderr nor to configured logging facilities) I'd suggest to provide it - it's overkill to dive into the manual to figure out why the process was killed - and assuming the reason is logged somewhere, it'd be nice to have a switch (e.g. `--debug-stdout`) to log to stdout regardless of which logging facility is configured in the configuration files.

I can't say - and am not eager to know - the reason why the process fails at this point, I'd prefer to seem this issue fixed and see it on my console :)

[1] or `Killed` or something similar, didn't investigate too deep because of https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1411431
