dirstate: make sure that status does not overlook the fallback flags

Without this extra checks, file with fallback flags change as the only change
would be overlooked.

In the future we might store proper data in the dirstate and do less lookup.
However, for now this will do to make sure that 6.0 is forward compatible with
later version.
