ci: add openssl-1.0.2-fips to fuzz test

[boquan-fang]

Description of changes:

buildspec_fuzz_batch.yml is lacking openssl-1.0.2-fips coverage. However, that libcrypto is tested in buildspec_omnibus.yml.

We need to add a test for openssl-1.0.2-fips in fuzz test to fill that coverage.

Call-outs:

AWS-LC fips is another fips libcrypto that we have. However, we are not testing that in fuzz test because of compilation issue. Refer to issue #4800 for detail description of that problem.

Testing:

This change will be tested in CodeBuild s2nFuzzBatch.
