upload_s3: provide git ish as argument (#169)

Browse source 
* upload_s3: provide git ish as argument

$GITHUB_SHA isn't the actual PR's HEAD's SHA, but a merge commit or
something.

* upload_s3: use an empty object if the file doesn't exist on s3

It's not pretty, but it works, and the md5sum of a file should never be
"null".

* release-branches: upload to `branch_${name}` instead
