commit-graph: store the hash algorithm instead of its length

The commit-graph stores the length of the hash algorithm it uses. In
subsequent commits we'll need to pass the whole hash algorithm around
though, which we currently don't have access to.

Refactor the code so that we store the hash algorithm instead of only
its size.
