test-runner: enable no_hash_pointers=1

Set no_hash_pointers=1 to avoid printk printing "___ptrval___" for %p.
This happens with test-runner since the kernel is not running long
enough to gather entropy and so refuses to print addresses, and makes
debugging harder.  As test-runner is only used for testing and
debugging, pointer hashing is not needed.
