libcrypto: add missing symbols to the fips provider

OpenSSL 3 supports a modular architecture, allowing different providers
to bring specific implementations of cryptographical algorithms. One
such provider, "fips", ships with OpenSSL 3 directly, and groups
algorithms that can be FIPS 140-2 validated.

The import of OpenSSL 3.0.9 was building this provider incorrectly,
missing symbols required for proper operation.

In addition, without the change in OpenSSL's crypto/bn/bn_const.c, the
FIPS module fails loading: Undefined symbol "ossl_bignum_modp_1536_p".
This change is consistent with crypto/bn/bn_dh.c though.
