api: apt: list_updates: fix dependency detection for virtual package

A virtual package does not have SelectedState Install, but the
dependency will still be satisfied if a package providing it has.

Fixes a bug, wrongly showing that postfix will be installed, when a
different mail-transport-agent is installed and a pve-manager update
is available:
