match: don't remove '.' from _includeroots

This makes _includeroots more like _fileroots and gives visitdir() a
nice symmetry in the two.

I'm hoping to later combine the two (_fileroots and _includeroots),
and having them treated similarly should make that step easier to
follow.

    suite.run(results)
    if results.errors or results.failures:
        for tc, exc in results.errors:
