Fix ftrace_format.py not reading from stdin

optee_os/scripts/ftrace_format.py does not read from stdin, hence piping into it does not work and only prints usage information. Instead, the ftrace-<ta_uuid>.out file has to be given as an argument. Signed-off-by: Stefan Gloor <[email protected]> Reviewed-by: Jerome Forissier <[email protected]>

     - Run helper scripts called ``ftrace_format.py`` to translate the function
       graph binary data into human readable text and ``symbolize.py`` to
       convert function addresses into function names:
-      ``cat ftrace-<ta_uuid>.out | optee_os/scripts/ftrace_format.py |
