mcstrans: silence -Wextra-semi-stmt warning

Browse Source 
On Ubuntu 20.04, when building with clang -Werror -Wextra-semi-stmt
(which is not the default build configuration), the compiler reports:

      mcstransd.c:72:35: error: empty expression statement has no effect;
      remove unnecessary ';' to silence this warning
      [-Werror,-Wextra-semi-stmt]
              log_debug("%s\n", "cleanup_exit");
                                               ^

Replace the empty log_debug substitution with a do { ... } while (0)
construction to silence this warning.
