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.

  $ hg init repo
  $ cd repo

  $ touch foo
  $ hg ci -Am 'add foo'
  adding foo

  $ hg up -C null
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

this should be stored as a delta against rev 0

  $ echo foo bar baz > foo
  $ hg ci -Am 'add foo again'
  adding foo
  created new head

  $ hg debugindex foo
     rev linkrev       nodeid    p1-nodeid    p2-nodeid
       0       0 b80de5d13875 000000000000 000000000000
       1       1 0376abec49b8 000000000000 000000000000
