packaging: always execute builddeb from source root
Without this, dockerdeb and the make targets that invoke it may
fail depending on the pwd at the time of invocation.

revlog: don't include trailing nullrev in revlog.revs(stop=len(revlog))
This was an odd side effect of the nullid entry that's in the
