util-linux: bump version and revamp options

Bump to latest 2.22.2 version and revamp available options.

* Remove the assumed enable/disable defaults since these seem to change
  quite often, so do what's wise and always enable/disable things.

* Switch from build "X" menu options to just X, add some help and sort.

* Introduce new option to install binaries (or not) to reduce bloat for
  packages that just need libblkid and/or libuuid.
