  -----------
  fix type casting in ossl_cmp_mock_srv_set1 functions

newer versions of clang trigger ubsan warnings on the following
functions:
ossl_cmp_mock_srv_set1_refCert
ossl_cmp_mock_srv_set1_chainOut
ossl_cmp_mock_srv_set1_certOut
ossl_cmp_mock_srv_set1_newWithNew
ossl_cmp_mock_srv_set1_newWithOld
ossl_cmp_mock_srv_set1_oldWithNew
ossl_cmp_mock_srv_set1_caPubsOut

Due to the fact that the respective function prototypes don't match the
callback function pointer prototypes (the former use concrete strucuture
types while the latter uses a void pointer).

Fix it by bifurcating setup_cert[s] (the call-in fuctions) to have
variants that accept the expected type and corresponding callback
signature so that the above functions can be used without thunking

Fixes openssl/project#1969
