Various incorrect binary name / target paths in benchmarks

[oliverchang]

These are leading to incorrect compilation results and/or incorrect targets being run.

e.g.

https://llm-exp.oss-fuzz.com/Result-reports/scheduled/2024-03-06-weekly-all/sample/output-picotls-ptls_handle_message/01
https://llm-exp.oss-fuzz.com/Result-reports/scheduled/2024-03-06-weekly-all/sample/output-minizip-mz_crypt_aes_set_decrypt_key/01
https://llm-exp.oss-fuzz.com/Result-reports/scheduled/2024-03-06-weekly-all/sample/output-nginx-ngx_http_grpc_pass/01

and more.

And obvious marker of these errors is when there is 100% build rate, but 0% coverage.
