largefiles: avoid exec-bit examination on the platform being unaware of it

Changeset 24600c9d7f4e introduced the examination of exec bit of
largefiles in "hg status --rev REV" case, but it doesn't avoid it on
the platform being unaware of exec-bit (e.g. on NTFS of Windows).

  $ hg init
  $ echo a > a
  $ hg add a
  $ hg commit -m test

Do we ever miss a sub-second change?:

  $ for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20; do
  >     hg co -qC 0
  >     echo b > a
  >     hg st
  > done
