source: Disable sources where we cannot find the command

So basically if something has not been installed, we won't try to
relaunch it again and again. But that also means that the daemon needs
to be restarted after something else has been added.

command: Map back any negative return codes

This is not perfect, but should be good enough since applications
normally don't use any return codes larger than 128.
