feat: build id

[caarlos0]

this is the first step to achieve multiple archives: we need to be able to identify builds.

The binary name alone is not a good idea, as the user may have different build configs depending on GOOS for example, so an ID field was added.

This is a breaking change: if the user has multiple builds with the same binary name the release will now fail.
