by calling `repo-process-deb` with trusty-unstable` rather than
`trusty` for unstable builds, because that seems to make sense.
To make sure, both are called. Same applies to stable.
as part of migrating most of my services to a new server,
I've switched CI to woodpecker, a fork of drone. CI configs are now in
.woodpecker/, and are neater. The server runs on arm64, so the configs
and prerequisite jfa-go-build-docker are built to run there primarily.
They should work on other platforms still.
New CI is at ci.hrfee.dev.
