1. daemon: overlay2: Write layer metadata atomically …

   When the daemon process or the host running it is abruptly terminated,
   the layer metadata file can become inconsistent on the file system.
   Specifically, `link` and `lower` files may exist but be empty, leading
   to overlay mounting errors during layer extraction, such as:
   "failed to register layer: error creating overlay mount to <path>:
   too many levels of symbolic links."
   
   This commit introduces the use of `AtomicWriteFile` to ensure that the
   layer metadata files contain correct data when they exist on the file system.
