Include FIPS mode in OpenSSL_version return value (#1419)

This change includes FIPS mode information in the return value of
`OpenSSL_version(OPENSSL_VERSION)`. This will allow consumers of CPython (and
likely other tools or language runtimes) to detect FIPS mode without calling to
an AWS-LC-specific API, which would require either patching or forking the
language or tool in question.
