ftrace/selftests: Change non-unique test symbol to init_once
The name_show symbol is not the best choise, because it often
appears only three times on s390 in kallsyms, with two of them
having module annotations [mdev] and [i2c_core].
Switch to init_once which has many more duplicate instances
all in vmlinux, making it a more reliable non-unique symbol
for testing kprobe registration failure.
