add a way for callback to disable itself

The idea is that some plugin would not be called in some
specific case, and the callback should decide by itself.

Having a way to globally disable it is much cleaner than
disabling every method one by one on the plugin side.

My use case is for fedora-infrastructure that cannot be run
from git checkout since it try to connect to the message bus,
but another case would be to bootstrap infrastructure, or to
run the code on a test servers without having all the callback
infrastructure setup.
Fixed usage comment to fish syntax for sourcing a file
add test for the disabling of callback plugins
- fixed typos and errors from feedback
- now makes sure a proper mask is added
- now captures I/O error produced when group, user or permissions are
  invalid

temporary file to validate.
