transaction: apply checkambig=True only on limited files for similarity

Now, transaction can determine whether avoidance of file stat
ambiguity is needed for each files, by blacklist "checkambigfiles".

For similarity to truncation in _playback(), this patch apply
checkambig=True only on limited files in code paths below.

  - restoring files by util.copyfile(), in _playback()
    (checkambigfiles itself is examined at first, because it as a
    keyword argument might be None)

  - writing files at finalization of transaction, in _generatefiles()

This patch reduces cost of checking stat at writing out and restoring
files, which aren't filecache-ed.
