makefile: Report correct tag in binary version

[Wondertan]

If there are several tags on the same commit(like -arabica and -mocha) it will always give the latest tag, even if you do git checkout tags/<tag> on a specific tag.

It's unclear to me right now how to solve that. One of the options is to ensure different tags are never on the same commit, but there might be an easier way.

I don't expect this to work in 100% of cases but I think it's an improvement over the current buggy version reporting: celestiaorg/celestia-app#3977
