localrepo: make restoring from backup at rollback avoid ambiguity of file stat

Rollback of previous transaction restores contents of files below by
renaming from 'undo.*' file. If renaming keeps ctime, mtime and size
of a file, restoring is overlooked, and old contents cached before
restoring isn't invalidated as expected.

  - .hg/bookmarks
  - .hg/phaseroots

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

BTW, .hg/dirstate is also restored at rollback. But it is restored by
dirstate.restorebackup(), and previous patch already made it invoke
vfs.rename() with checkambig=True.

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