metadata: filter the `removed` set to only contains relevant data The `files` entry can be bogus and contains too many entries. This can badly combines with the computation of `removed` inflating the set size. The can lead to the changesets centric rename computation to process much more data than needed, slowing it down (and increasing space taken by data storage). In practice newer commits already that reduced set, this applies this "fix" to older changeset. Differential Revision: https://phab.mercurial-scm.org/D8589
