match: fix the rust-side bug in visit_children_set for rootfilesin matchers

The fix is checked by `test_pattern_matcher_visit_children_set` test,
which is what caught the bug in the first place, but also by an end-to-end
test that I made for this purpose.

Accept the new results of Cargo tests

Many of these were already annotated with "FIXME", which is a good sign.
