selftests/ftrace: Add new test case which checks non unique symbol
If name_show() is non unique, this test will try to install a kprobe on this
function which should fail returning EADDRNOTAVAIL.
On kernel where name_show() is not unique, this test is skipped.

We will probably need to bisect the kernel between these two tags.
