hfsplus: return file attributes on statx
The immutable, append-only and no-dump attributes can only be retrieved with an ioctl; implement the ->getattr() method to return them on statx. Do not return the inode birthtime yet, because the issue of how best to handle the post-2038 timestamps is still under discussion. This patch is needed to pass xfstests generic/424.
