build: move OPENSSL_API_COMPAT to else clause
Currently there are a number of deprecation warnings generated when linking with OpenSSL 3.0, for example:
In file included from ../src/crypto/crypto_scrypt.h:6,
from ../src/crypto/crypto_scrypt.cc:1:
../src/crypto/crypto_util.h:64:37: warning:
‘void RSA_free(RSA*)’ is deprecated: Since OpenSSL 3.0
[-Wdeprecated-declarations]
64 | using RSAPointer = DeleteFnPtr<RSA, RSA_free>;
The reason for this is that I had placed the macro OPENSSL_API_COMPAT
inside of the node_shared_openssl="false" clause, but that was a
mistake and this macro should have gone into the else clause instead.
