cache: avoid warming the fnodetags cache after clone
That cache can quite expensive to compute on large repository as not that `hg
clone` is warming all cache, this can introduces a significant slowdown for
clone time[1]. As a stop gap measure introduce a quick fix for
that on stable, skipping the fnodetags cache post-clone.
