[PATCH 2/8] commit-graph: read `OIDF` chunk with `pair_chunk_expect()`

[Taylor Blau <me@ttaylorr.com>]

The `OIDF` chunk can benefit from the new chunk-format API function
described in the previous commit. Convert it to `pair_chunk_expect()`
accordingly.

While we're at it, let's mark the error() string for translation.
