Fixtures: systemd 257 show captures and pre-cut observation records

Real systemctl show output (Vili presence-only, Odin with one service
credential) and the two MessagePack encodings of a pre-cut observation, as
inputs for the credential-evidence cut. Nothing reads them yet.

+encodings of a `SystemdWorkloadObservation` with `load_credential` set to
+`[unprintable]`, produced by the code at `112a7a5` (the form live incumbents
+persisted). They pin that later Idunns still decode such records.
