Subject: [PATCH] bootctl-uki: several follow-ups for inspect_osrel()
Follow-ups for #26124 and #26158.
- use os_release_pretty_name(),
- constify the buffer passed to inspect_osrel(),
- propagate errors in inspect_osrele(), and ignore them in the caller
side,
- and several coding style fixlets.
(cherry picked from commit 1b7586df976d7b033b4901a099337d83578bb8f1)
