  test: Remove args[3] from sdt:task::task_rename probe

Commit e3f6a4227 ("tracing: Remove pid in task_rename tracing output")
of the Linux kernel (6.14-rc1) removed the pid (first) argument to the
task_rename tracepoint.  The corresponding DTrace sdt probe, therefore,
has one less argument.  Change the test to omit args[3], regardless of
the kernel version.

Change the test to emit more diagnostic output in case of failure.

Commit 564efa04c ("test: adjust sdt.tst.args.d for task_rename
tracepoint differences") of DTrace already handles this task_rename
issue for test/unittest/sdt/tst.args-*.d by simply skipping one test
or the other depending on whether the kernel version is < or >= 6.14.
