It's useful to distinguish the failure to find updates. This carries
over the ability for pacman -Qu to return errors when no upgrades are
available.

At the same time, this should (unlike pacman -Qu) use its own unique
return code, since checkupdates may error for a couple of reasons
including download issues.

Fixes FS#64219
