swapon: annotate column header names with OSC8 hyperlinks

Column header names are annotated with OSC8 hyperlinks to
provide tooltips with a description of the column.

This is mainly motivated by the fact that column headers
are currently not translated, so as an alternative we will
provide a column description translated according to the
environment locale setting.
