This happens with flake jobsets for obvious reasons (namely, that nixexprinput
and nixexprpath may be undefined for a flake jobset).

At the moment, aggregate jobs can easily break and cause the entire
evaluation to fail, which is not ideal. For Nixpkgs, we do have some
important aggregate jobs (like `tested`), but for debugging and building
purposes it's still useful to get a partial result even if the channel
won't actually advance.
This commit changes the behaviour of hydra-eval-jobs such that it
aggregates any errors found during the construction of an aggregate, and
will instead annotate the job with the evaluation failure such that it
shows up in a "cleaner" way.
There are really two types of failure that we care about: one is where
the attribute just ends up missing altogether in the final output, and
also where the attribute is in the output but fails to evaluate. Both
are handled here.
Note that this does mean that the same error message may be output
multiple times, but this aids debuggability because it'll be much
clearer what's blocking the job from being created.
At the moment, the jobset object is unlikely to actually retrieve the
evaluation error output, because it isn't refreshed after
hydra-eval-jobsets is run.
Explicitly calling DBIx::Class::Row->discard_changes causes any updated
data to be refreshed, at the cost of losing any not-yet committed
changes to the row.
