bitbake: toaster: attach kernel artifacts to targets

The bzImage and modules files were previously attached to a build,
rather than to the target which produced them. This meant it was
not possible to determine which kernel artifact produced by a
build came from which target; which in turn made it difficult to
associate existing kernel artifact with targets when those
targets didn't produce artifacts (e.g. if the same machine + target
combination was built again and didn't produce a bzImage or modules
file because those files already existed).

By associating kernel artifacts with the target (via a new
TargetArtifactFile model), we make it possible to find all
the artifacts for a given machine + target combination. Then, in
cases where a build is completed but its targets don't produce
any artifacts, we can find a previous Target object with the same
machine + target and copy its artifacts to the targets for a
just-completed build.

Note that this doesn't cover SDK artifacts yet, which are still
retrieved in toaster.bbclass and show up as "Other artifacts",
lumped together for the whole build rather than by target.
