[PATCH v2 6/6] test: fix trace_autotest_with_traces parallel execution

Stephen Hemminger

The trace_autotest_with_traces test needs a unique file-prefix to avoid
collisions when running in parallel with other tests.

Rather than duplicating test argument construction, restructure to add
file-prefix as the last step. This allows reusing test_args for the
trace variant by concatenating the trace-specific arguments and a
different file-prefix at the end.

Fixes: 0aeaf75df879 ("test: define unit tests suites based on test types")
