t5319: make test work with SHA-256

This test corrupts various locations in a multi-pack index to test
various error responses.  However, these offsets differ between SHA-1
indexes and SHA-256 indexes due to differences in object length.  Use
test_oid to look up the correct offsets based on the algorithm.
