obsstore: make the invalid markers check wrap-able

Some evolve user ignored the invalid markers for about two years and still have
some of them in some repository. This lead to plain abort whenever mercurial try
to open such repo. We need reinstall some way to clean this up in the evolve
extension. For this purpose, we need the checker code wrap-able independently.

This is scheduled for stable as this issue is blocking some evolve user.
