dirstate: make restoring from backup avoid ambiguity of file stat

File .hg/dirstate is restored by renaming from backup in failure
inside scopes below. If renaming keeps ctime, mtime and size of a
file, restoring is overlooked, and old contents cached before
restoring isn't invalidated as expected.

  - dirstateguard scope (from '.hg/dirstate.SUFFIX')
  - transaction scope (from '.hg/journal.dirstate')

To avoid ambiguity of file stat at restoring, this patch invokes
vfs.rename() with checkambig=True.

This patch is a part of "Exact Cache Validation Plan":
