Code review comment for ~jocave/plainbox-provider-resource:use-distro-if-available

Using distro module will imply having to deal with this bug: https://github.com/nir0s/distro/issues/260

There's a patch in checkbox-core-snap:

Not sure if we will face it on deb checkbox but it could be a good idea to catch subprocess.CalledProcessError in the resource code and fallback to the old code.
