  test: adjust sdt.tst.args.d for task_rename tracepoint differences

As of kernel 6.14, the task_rename tracepoint provides only 3 arguments
rather than 4 (the pid got dropped).

    A test/unittest/error/tst.trace_string.d

  Log Message:
  -----------
  Pad strings in the output buffer with NUL bytes after terminating byte

The consumer checks if there are non-NUL bytes after the terminating
NUL byte to decide whether to print the contents of the output buffer
as a string or as raw bytes.  So, for strings, make sure that the
string is padded with NUL bytes.

A robust test that shows the problem can be hard to devise.  Some tests
encounter the problem.  This patch adds another test that might show
the problem.
