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

[Stephen Hemminger <stephen@networkplumber.org>]

The trace_autotest_with_traces test was reusing the test_args array
from trace_autotest, which already contained --file-prefix=trace_autotest.

Fix by building trace_args from scratch for the _with_traces test
variant instead of appending to the existing test_args array.

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