fsck: suppress commit-graph output with --no-progress

Since e0fd51e (fsck: verify commit-graph, 2018-06-27), `fsck` runs
`git commit-graph verify` to check the integrity of any commit-graph(s).

Originally, the `git commit-graph verify` step would always print to
stdout/stderr, regardless of whether or not `fsck` was invoked with
`--[no-]progress` or not. But in 7371612 (commit-graph: add
--[no-]progress to write and verify, 2019-08-26), the commit-graph
machinery learned the `--[no-]progress` option, though `fsck` was not
updated to pass this new flag (or not).

This led to seeing output from running `git fsck`, even with
`--no-progress` on repositories that have a commit-graph:

    $ git.compile fsck --connectivity-only --no-progress --no-dangling
    Verifying commits in commit graph: 100% (4356/4356), done.
    Verifying commits in commit graph: 100% (131912/131912), done.

Ensure that `fsck` passes `--[no-]progress` as appropriate when calling
`git commit-graph verify`.
