protocol_examples_common: keep buffering enabled on stdout

Browse Source 
- Newlib uses significantly more stack space when printing to an unbuffered stream
- For examples tests, disabling buffering on stdout is not really required

This issue was found during one of the OTA example test failure, root cause
being stack overflow in `esp_event` task.
