package-version-list held every installed package and both outputs were
identical. Outputs also carried arch suffixes inconsistently and followed
install order.
- package-version-list lists only requested packages; all-package-version-list
lists every installed package.
- Entries are name=version, with :arch only for packages installed for a
non-native architecture (e.g. libc6:i386), so native output matches v1.
- Entries are sorted with PackageName.compareTo.
- Requested packages are matched by name, and by arch when both specify one.
