[cmake] remove --long from version.cmake

This means if someone checks out a tagged revision, the extra commit N
and commit hash are removed from the VERSION, leaving just the tag name

Adding any commits will cause -<commitssince>-g<commithash> to return.

The dirty worktree '+' still functions as normal, simply appended to
the end of the tag name, like 'v1.0.3+'. With both extra commits and a
dirty worktree, it will look like 'v1.0.3-2-gd6e00e4f34a+', as usual.
