* Detect failed sysvinit module
- This checks the stderr instead of the rc to detect whether the
sysvinit module was successful or not, as even when failing, the
rc would be 0.
- It immediatly became obvious that the debug info when failing
was far too little to properly debug the role. To improve this,
I also added the rc, stderr and stdout to the debug output.
* Revert stderr check to rc check, rename out->stdout, err->stderr
* Do not compare result to unset parameter in sysvinit module
* Fix misformed command in sysvinit module
* Small None-comparison style fix in sysvinit module
