Fix the M:N SQL join in RebuildImagesOnODCSComposeDone.
The old code did not join with ArtifactBuildCompose but only with
Compose. The ArtifactBuild to Compose mapping was therefore wrong
and the SQL query returned all the PLANNED ArtifactBuilds no matter
what the compose ID was.
In this commit, the ArtifactBuildCompose join is added and only
ArtifactBuilds with matching compose ID are returned as expected.
