pikpak: fix cid/gcid calculations for fs.OverrideRemote
Previously, cid/gcid (custom hash for pikpak) calculations failed when attempting to unwrap object info from `fs.OverrideRemote`. This commit introduces a new function that can correctly unwrap object info from both regular objects and `fs.OverrideRemote` types, ensuring uploads with accurate cid/gcid calculations in all scenarios.
