update: filter the ambiguous mtime in update directly
Right now, this filtering is done by `dirstate.write` using the time of
`dirstate.write` method call. However that filtering is done "too late"
It works "fine" as most command are "fast enough", and race rare enough.
We are about to change the mtime filtering logic in the dirstate to be more
accurate and reliable.
However `hg update` will still need such filtering (mostly because it is
actually quite racy, even with the existing filtering). So we explicitly
implement a similar logic here. Before removing the older one later in the
series.
