sensors_temperatures: also search /sys/devices/platform/coretemp.* for temperatures

[karabijavad]

On my machine, the /sys/class/hwmon/hwmon*/device/ directories do not contain temp*_*.
However, I did find them at /sys/devices/platform/coretemp.0/

This PR adds /sys/devices/platform/coretemp./hwmon/hwmon/temp*_* to the list of files to search for in sensors_temperatures.
