Subject: [PATCH] dissect-image: validate extension-release even if the host
 has only ID in os-release

A rolling distro won't set VERSION_ID or SYSEXT_LEVEL in os-release,
which means we skip validation of ExtensionImages.
Validate even with just an ID, the lower level helper already
recognizes and accepts this use case.

Fixes https://github.com/systemd/systemd/issues/22146
