perf: fallback to subset if ondisk cache is missing in perfbranchmapload
If there is no branchmap on disk for that filter, it means that the cache from
some subset's filter is relevant for this one. We look for it instead of
aborting.
That way it is much simpler to run the command in an automated way. We can now
add it to `test-contrib-perf.t`.

"""Generate release notes from our commit log.
This uses the relnotes extension directives when they're available,
and falls back to our old pre-relnotes logic that used to live in the
release-tools repo.
