mod_blocklist: Add option 'migrate_legacy_blocking' to disable migration from mod_privacy
Tiny performance improvement for new users by skipping this check. Most
servers should have gone trough the migration for all active users long
ago.
As a suitable first step of phasing out this code, we make it possible
to disable it first. Later it can be disabled by default, before finally
the code is deleted.
