odb: fix printf formatter for git_off_t

The fields `declared_size` and `received_bytes` of the `git_odb_stream`
are both of type `git_off_t` which is defined as a signed integer. When
passing these values to a printf-style string in
`git_odb_stream__invalid_length`, though, we format these as PRIuZ,
which is unsigned.

Fix the issue by using PRIdZ instead, silencing warnings on macOS.
