ci: add awslc-fips and openssl-1.0.2-fips to valgrind

[boquan-fang]

Description of changes:

Compared Libcryptos that are used in buildspec_omnibus.yml and buildspec_valgrind.yml, I found out that FIPS libcryptos for awslc-fips and openssl-1.0.2-fips are missing in buildspec_valgrind.yml. This PR addresses that problem and add checks for those two Libcryptos.

Add S2N_LIBCRYPTO = awslc-fips and openssl-1.0.2-fips to buildspec_valgrind.yml. Hence, buildspec_valgrind.yml will have the same libcrypto coverage as the one in buildspec_omnibus.yml.

Call-outs:

• An individual Valgrind check has been fully integrated into the github CI and release process CI. See PR#4851 and PR#4776. So, we should remove relevant parts of Valgrind (which is everything about Valgrind after this PR is merged) in buildspec_omnibus.yml and buildspec_generalbatch.yml. This should be followed up by future PRs.

Testing:

Tests for success:

• This PR is tested by the Valgrind Codebuild Job.

Tests for intentionally leaking memory:

• I remove the DEFER_CLEANUP for a s2n_external_psk_new() here:
  • https://github.com/boquan-fang/s2n-tls/blob/d219c10e592959a7878f48d670e2c73abd3319de/tests/unit/s2n_early_data_test.c#L263
  • This change should makes the s2n_early_data_test.c intentionally leaks memory.
  • The test can capture that leaking memory.
    • Test result is in this CodeBuild Job.
