The error message in the daemon() failure path uses %p format specifier
without providing a corresponding pointer argument, resulting in undefined
behavior and printing garbage values.
Replace %p with %m to properly print the errno error message, which is
the intended behavior when daemon() fails.
This fix ensures proper error reporting when daemonization fails.

Enhance the thermal-engine skeleton with the thresholds added in the
kernel and use the API exported by the thermal library.

This change provides a simple daemon skeleton. It is an example of how
to use the thermal library which wraps all the complex code related to
the netlink and transforms it into a callback oriented code.
The goal of this skeleton is to give a base brick for anyone
interested in writing its own thermal engine or as an example to rely
on to write its own thermal monitoring implementation.
In the future, it will evolve with more features and hopefully more
logic.
