Better interop with s3fs-fuse

AFAICT through testing, https://github.com/s3fs-fuse/s3fs-fuse is the only currently working and developed fuse filesystem for s3. In order to better interoperate with then I suggest setting the following additional metadata in a way compatible with that tool

x-amz-meta-gid x-amz-meta-mtime x-amz-meta-uid x-amz-meta-mode / x-amz-meta-permissions

Good point. Previously, we tried to be compatible s3cmd, which has its own implementations. I'll look into s3fuse's implementation in this case.
