loader: Simplify additional description definition

Let's modify the `make_broken` function to optionally accept
`description` which is used to report additional comments after the test
uid, instead of doing this manually per each call.

This also replaces the same parameter for the dummy `ignore_broken`
function which still contained other optional parameter not used by the
parallel `make_broken` function.
