bundle: support fsck message configuration

The git-index-pack(1) spawned during `unbundle()` can be optionally
configured with `--fsck-objects` to perform fsck checks on the bundle.
This does not propagate fsck message severity configuration though.

Extend `verify_bundle_opts` to store this information and update
`unbundle()` to configure the `--fsck-objects` option appropriately.
