Allow signoff to be added when one already exists on a precursor.

The current obsolescence support makes little difference between
comments/signoff from a cset and the ones from its predecessors.

This patch avoid a signoff from a precursor to be seen as changeable, and allow
the user to re-signoff on the latest version of the changeset.
