Daniel Lezcano 3b7c5e8adf tools/thermal: Add util library

The next changes will provide a couple of tools using some common
functions provided by this library.

It provides basic wrappers for:

 - mainloop
 - logging
 - timestamp

Use DESTDIR for installing into a different root directory.

This is useful for building a package. The program will be

installed in this directory as if it was the root directory.

Then the build tool can move it later.
