Use git describe --tags to include non-annotated tags

By default, `git describe` uses only annotated tags. Since some may not
be annotated (like v1.10) this causes some scripts to pick a confusing
version identifier.

This patch fixes the issue by passing `--tags`, which means all tags
will be considered.
