add a new record flag CTDB_REC_FLAG_VACUUM_MIGRATED.

This is to be used internally. The purpose is to flag a record
as been migrated by a VACUUM_MIGRATION, which is triggered by
a VACUUM_FETCH message as part of the vacuuming. The local store
routine will base its decision whether to delete or to store
the record (among other things) upon the value of this flag.

This flag should never be stored in the local database copies.
