[PDK-6682][DSS APP]Display sample application is printing wrong number of frames...

- Reduced test time from 120 seconds to 30 seconds
- Issue:
    - Sample application was printing wrong number of frames displayed
- Root-cause
    - App has an additional layer on top of normal UART/CIO print statements
    - Argument parsing done in this function was incorrect
- Resolution:
    - Add 'vsnprintf()' along with 'va_start()' and 'va_end()' for argument parsing
