object-file: pass filename to fsync_or_die

If we die while trying to fsync a loose object file, pass the actual filename we're trying to sync. This is likely to be more helpful for a user trying to diagnose the cause of the failure than the former 'loose object file' string. It also sidesteps any concerns about translating the die message differently for loose objects versus something else that has a real path.
