PPP, PPPoS: Use const void* instead of u8_t* in pppos_output_cb_fn()

Browse Source 
There is no good reason why this function should take a non-const
pointer, as the output callback should never modify what lwIP gives it.
While changing that also switch to a more generic `void*` instead of
"byte".
