Initialization logs for xeus-cpp-lite are treated as errors

[anutosh491]

This is what I see when I start lite

Not sure why these logs like the cc1 command etc are treated as errors.

This is what I see for other kernels.

For eg

1. xeus-r-lite shows this

2. The python-pyodide kernel shows this

This is now fixed.
