hddtemp plugin, collectd.conf(5): Added "TranslateDevicename" config option.

If enabled, translate the disk names to major/minor device numbers. For
backwards compatibility this defaults to true but it it recommended to disable
it as it will probably be removed in the next major version. Any other parts
of collectd have changed in a similar way with version 4.0, so hddtemp should
do so as well.

This option is disabled in new versions of the config file.
