Porting coreth 0.13.7 to OpenBSD adJ 7.5

% go mod edit --replace "github.com/ava-labs/[email protected]"="github.com/vtamara/[email protected]"
% ./scripts/build.sh

After I updated avalanchego 1.11.10adJ to use my fork of coreth at v0.13.7adJ

To test I removed -race from scripts/build_test.sh and run it.

Since coreth implements contracts chain i.e c-Chain in Avalanchego, we think it should answer to requests to that API.

A test node that validated in testnet (not during this test) to a request exemplified at https://docs.avax.network/reference/avalanchego/c-chain/api responds with:
