Fix type cast in SSL_CTX_set1_groups macro

The macro casts the glist parameter to char*
instead of (int *) like the documentation of the function suggest.

Also the function tls1_set_groups that is called from SSL_CTX_ctrl
takes an int * argument. This looks like a copy&paste error from
SSL_CTX_set1_groups_list function.
