commands: use revlog._deltachain in debugdeltachain
We have a nice API now. Use it.
This does mean we introduce an extra index lookup for each revision.
Considering this is a debug command, the overhead should be acceptable.
We could add the chain size to revlog._deltachain(). However, that
feels like avoidable overhead.
