util-linux: revise contents and short descriptions

* tailf is removed completely
* fdformat is disabled by default, and we don't really have any reason
  to enable it (and we'll need to workaround the missing man page issue
  if we want to enable it)
* irqtop, lsirq, scriptreplay, and uclampset added
