'apt list' should have at least 2 keys:
- 'apt list --upgradable' to show packages that will be upgraded;
- 'apt list --kept-back' to show packages on hold (= 'apt-mark showhold');
- 'apt list --upgradable --kept-back' to show both (i.e. union).
And 'apt update' should report only '--upgradable' packages (not '--upgradable' + '--kept-back').
