filectx: use linkrev to sort ancestors

We're going to make rev() lazily do _adjustlinkrevs, and we don't want
that to happen when we're quickly tracing through file ancestry
without caring about revs (as we do when finding copies).

This takes us back to pre-linkrev-correction behavior, but shouldn't
regress us relative to the last stable release.
