Subject: [PATCH] fix discover_lintables: strip ./ from WcMatch return value

calling WcMatch('.', ...) causes the resulting file names to be prefixed
with `./`.
If the tests are run in a git-repository, this is not an issue, as git
is preferred of WcMatch in the code.

Therefore remove the `./` prefix from the WcMatch return value to get
the identical expected output.
