commit-graph: add base graphs chunk
To quickly verify a commit-graph chain is valid on load, we will read from the new "Base Graphs Chunk" of each file in the chain. This will prevent accidentally loading incorrect data from manually editing the commit-graph-chain file or renaming graph-{hash}.graph files. The commit_graph struct already had an object_id struct "oid", but it was never initialized or used. Add a line to read the hash from the end of the commit-graph file and into the oid member.
