pidof: show worker threads

Reimplementation of pidof for procps toolset contains sort of deactivated code and does not return results for processes without task.cmdline entry (usually kernel worker threads). Old pidof and pgrep do that in comparison. Despite all perks provided by using pgrep instead, pidof should show those workers again.
