[bug#59716] [PATCH] Add tes3mp

[Michal Atlas <michal_atlas+git@posteo.net>]

* gnu/packages/game-development.scm (set-openmw-commit-version): New private-variable
* gnu/packages/game-development.scm (set-commit-version): New phase in tes3mp and tes3mp-server

---

Sorry,
I didn't notice that the official release tarball was from
tag `tes3mp-0.8.1` and not `0.8.1`.

On that note, I forced in version information to be able to
connect to standard 0.8.1 server instances from the binary release.
They'd refuse connection due to "version mismatch" otherwise.

Hardcoding the COMMITHASH is certainly ugly,
but the TAGHASH probably needs to be as well anyways, since
cmake normally generates it by running `git rev-list --tags --max-count=1` on the repo,
which I'm not sure if we want to do or can do in the build itself,
this at least ensures that the correct tag is always chosen.

Cheers.
