When running rtla as

    `rtla <timerlat|osnoise> <top|hist> -t custom_file.txt -a 100`

-a options override trace output filename specified by -t option.
Running the command above will create <timerlat|osnoise>_trace.txt file
instead of custom_file.txt. Fix this by making sure that -a option does
not override trace output filename even if it's passed after trace
output filename is specified.

This part is good, the only problematic bit was the clear_terminal stuff.
