selftests/ftrace: Fix to test kprobe $comm arg only if available
[ Upstream commit 2452c96e617a0ff6fb2692e55217a3fa57a7322c ]
Test $comm in kprobe-event argument syntax testcase
only if it is supported on the kernel because
$comm has been introduced 4.8 kernel.
So on older stable kernel, it should be skipped.
