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.
