tests: Write GTK locations into debug log in key_lifetime_in_memory

It looks like it is possible for the GTK to be found from memory every
now and then. This makes these test cases fail. Write the memory
addresses in which the GTK was found to the log to make it somewhat
easier to try to figure out where the key can be left in memory.
