Bug#24121 Incorrect test for SSL_VERIFY_SERVER_CERT

 - Interpret the pointer passed to 'mysql_options' for
   MYSQL_OPT_SSL_VERIFY_SERVER_CERT as a my_bool
 - In 5.1 the mysql_options signature will be chanegd to take
   a 'void*' in order to further emphasize the need for a pointer
   to correct type


client/mysqltest.c:
  Turn on ssl_verify_server_cert for all connections to "localhost"
  in mysqltest
sql-common/client.c:
  The pointer passed to 'mysql_options' for MYSQL_OPT_SSL_VERIFY_SERVER_CERT
  should be interpreted as a my_bool pointer (aka char*).
