  lib-storage: Don't enable modseqs on STATUS_HIGHESTMODSEQ.

This is requested always by IMAP's SELECT command even when the IMAP client
hasn't requested it. We don't want to unnecessarily enable modseqs that use up
memory and disk space when they're not really needed. Other callers may also be
interested in asking for HIGHESTMODSEQ (which is nowadays actually always
available) without enabling full modseq tracking.
