Reformat two lines flagged by the current rustfmt (fix CI fmt check)

The CI 'cargo fmt --check' gate failed on two pre-existing lines in
src/output/vcf/records.rs and tests/integration.rs that the current
stable rustfmt (1.8.0) wraps differently. Apply the formatting so the
workspace is fmt-clean; no logic change.
