Our tests should already be pretty extensive,
and any bug fixes should result in more regression test cases,
but testing against a few diverse and popular third party modules
will help prevent unintended regressions while developing garble.
The list is short for now. More can be added later.
This adds protobuf and wireguard from the original issue,
but not cobra and logrus, as they aren't particularly complex nor add
significant variety on top of protobuf and wireguard.
While here, we remove the job that only runs crlf-test.sh,
as we don't really need a separate job for a tiny script.
Fixes#240.
