chore: add publishing Makefile targets (#955)

If there are any files publishable to S3 then a `publish-aws-s3` target will
automagically exist, and similarly if there are any files publishable to
Bintray then a `publish-bintray-debian` target will automagically exist.
Like all phony targets, these get displayed by `make help` when available.
