Different derivations may result in a same build output. If a job registers a
derivation D2 with the output O1, Cuirass may already have processed another
derivation D1 with the same O1 output.

In that case, the new job must point to the D1 derivation and not the D2
derivation, for which no build will be triggered.

Each evaluation registration produces a list of new jobs. Until now, only the
jobs which build outputs were not stored in the "Outputs" table were added to
the "Builds" table.

It means that Cuirass looses track of the job list associated to a given
evaluation.  This is problematic to provide the overall build status of an
evaluation or to find the evaluation providing the best build coverage.

Add a new "Jobs" table that stores the job list of each evaluation.  Also add
a new "/api/jobs" API to consult it.
