[dts] [PATCH for-next v3 4/7] tests/TestSuite_nic_single_core_perf: Use user-specified output dir

[Patrick MacArthur]

The user can override the default output directory via a command line
argument, but this script does not account for that. Fix the script to
look up the output directory that the user requested and place the
custom output file in that directory.
