setup: make the version computation process more resistant
The tag fetching might return and empty string¹, from there everything derails
quickly. As setup tools becomes more picky about version format we make the
whole seems a bit more robust.
The resulting version will be obviously weird, but at least it will actually
install itself.
[1] This is a problem we will address in the next changesets.
