So far, all output created by scripts run with micrond has been
discarded. Since there is no reason for that and it also does not
match the expected behavior, this enables both stdout and stderr
output for the service.

If not desired, a user can still use >/dev/null or similar in his/her
micrond jobs to disable output easily and similar to what it would be
on other systems.
