Implement ubiquity-os logger instead of console logs

          It's the kernel so our logger instance does not exist here, but yes ideally we should use it.

Currently the kernel uses plain console.log to log messages. We should implement https://github.com/ubiquity-os/ubiquity-os-logger for more detailed / prettier logs.
