Issue1790: dirstate entry locked into unset if file mtime is set into

the future

Prepare test repo:

  $ hg init u

  $ cd u

  $ echo a > a

  $ hg add

  adding a

  $ hg ci -m1

Set mtime of a into the future:

  $ touch -t 202101011200 a

Status must not set a's entry to unset (issue1790):

  $ hg status

  $ hg debugstate

  n 644          2 2021-01-01 12:00:00 a

Test modulo storage/comparison of absurd dates:

#if no-aix

  $ touch -t 195001011200 a

  $ hg st

  $ hg debugstate

  n 644          2 2018-01-19 15:14:08 a
