Define OPENSSL_API_COMPAT
This avoids deprecation warnings from newer OpenSSL versions (3.0.0 in
particular).
This has been originally applied as 4d3db13 for v14 and newer versions,
but not on the older branches out of caution, and this commit closes the
gap to remove all these deprecation warnings in all the branches still
supported.
OPENSSL_API_COMPAT's value is set based on the oldest version of OpenSSL
supported on a branch: 1.0.1 for Postgres 13 and 0.9.8 for Postgres 11
and 12.
