SystemV service template does not actually generate any logs

[timcharper]

Expected behaviour

Logs should be generated to the specified file when daemonStdoutLogFile := Some("appname") is provided

Actual behaviour

The file is not created and all process output is discarded.

I wonder if the assumption is flawed in that redirects are assumed to be specifiable via an environment variable:

For example, the below program does not output to greetings.txt, is simply outputs hello >> greetings.txt

#!/bin/sh
args=">> greetings.txt"
echo hello $args

I can provide a repro case, if helpful. Getting a SystemV OS with OpenJDK 8 is a bit of a feat, I am not sure the best way to write an integration test for this.

Sorry for the late reply here as well 😢 and thanks for the pull request.
Integration tests are really hard for these ones and SystemV is really messy, so
I'm fine with releasing your change and see if others have issues with the new
way of starting the service. Thanks for the detailed commit message with the
related SO question 😍
