To ensure that manifests get random(ish) and stable UUIDs we set the rng seed arg based on the filename.

This should fix the issue discovered in
osbuild/manifest-db#124

that duplicated UUIDs for xfs/btrfs can trigger random(ish) and hard to diagnose errors.

This is the same as
osbuild/osbuild-composer#4124 hopefully for the right place this time.

We should also do the same in cmd/build for consistency (see also #88).

Thank you! I wasn't aware of this - I reworked this in #674 now
