Add additional parameter to dsa_builtin_paramgen to output the generated
seed to: this doesn't introduce any binary compatibility issues as the
function is only used internally.
The seed output is needed for FIPS 140-2 algorithm testing: the functionality
used to be in DSA_generate_parameters_ex() but was removed in OpenSSL 1.0.0
