dirstate.walk: don't report same file stat multiple times
dirstate.walk() generates pairs of filename and a stat-like
object. After "hg mv foo Foo", it generates one pair for "foo" and one
for "Foo", as it should. However, on case-insensitive file systems,
when it tries to stat to get the disk state as well, it gets the same
stat result for both names. This confuses at least
scmutil._interestingfiles(), making it think that "foo" was forgotten
rather than removed. That, in turn, makes "hg addremove" add "foo"
back, resulting in both cases in the dirstate, as reported in
issue4590.
This change only takes care of the "if unknown" branch. A similar fix
should perhaps be applied to the other branch.
