hddtemp_smartctl: support /dev/disk/by-id/* name translation

[nachtgeist]

If translate_names is set, for each drive walk the symlinks created by udev below /dev/disk/by-id/ and replace the simple device name sdX by its correspondent.

That way, graphs won't jump around between devices if the simple device names are unstable between reboots.
