Francis Laniel 09bcf92548 selftests/ftrace: Add new test case which checks non unique symbol
[ Upstream commit 03b80ff8023adae6780e491f66e932df8165e3a0 ]

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.
