t5318-commit-graph: remove unused variable

This is a remnant from early versions of the commit-graph patch series
[1], when 'git commit-graph --write' printed the hash of the created
commit-graph file, and tests did look at the command's output, because
the commit-graph file's name included that hash as well.
