dirstate-v2: add test that shows a collision in ignore patterns hash

This hash is used for optimizing dirstate `status`. We demonstrate that the
hash is incorrectly ignoring the changes to the semantics of the ignore
files just because the contents (but not their source) haven't changed.

This is fixed in the next changeset.
