tools/thermal/thermal-engine: Fix format string bug in thermal-engine 



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.
