crypto: use EVP_PKEY_CTX_set_dsa_paramgen_q_bits when available

This matches the formulation described in the documentation: https://www.openssl.org/docs/man3.0/man3/EVP_PKEY_CTX_set_dsa_paramgen_q_bits.html

It is also, starting OpenSSL 3.0, more type-safe because the wrapper macros were finally converted to real functions. In OpenSSL 3.0, it is also no longer quite a wrapper over EVP_PKEY_CTX_ctrl, so using this name saves some extra OSSL_PARAM <-> EVP_PKEY_CTRL conversions.

Alas, it was only backported to OpenSSL 1.1.1e, so I've left a temporary compatibility define until you all decide to drop pre-1.1.1e releases of 1.1.1.
