test: a fixture that cannot fail needs no guard

Browse Source 
ximbegin took a struct ct* only to USED() it and always returned 1, so
its seven `if(!ximbegin(...)) goto cleanup;` call sites tested nothing
and three of the cleanup labels they jumped to were unreachable.
ibusbegin malloc'd one byte twice so that its two fake DBusConnections
would differ by address, then CT_CHECKed the mallocs; two bytes in the
fixture are two addresses, and nothing has to be freed.
