Add an index on the logs_archived boolean on a RepositoryBuild

Browse source 
Addresses the slow query:

```
SELECT `candidates` . `id` FROM ( SELECT `t1` . `id` FROM `repositorybuild` AS `t1` WHERE ( ( ( `t1` . `phase` IN (...) ) OR ( `t1` . `started` < ? ) ) AND ( `t1` . `logs_archived` = ? ) ) LIMIT ? ) AS `candidates` ORDER BY `Rand` ( ) LIMIT ? OFFSET ?
```

While the cardinality on `logs_archived` will be low, it should also only be in the `false` state for a very small number of records, so it should make this query very, very fast.
