alpine: Use docker build --iidfile

Browse Source 
This was added in 17.06 and allows us to avoid using `$(BASE):build` which is
not safe against parallel builds etc.

Having done this restructure the build to not always delete the built container
and to separate out the `hash` and `version` file rules so that they can be
included in both the `tag` and `push` targets.
