Minor VFS2 xattr changes.
- Allow the gofer client to use most xattr namespaces. As documented by the
updated comment, this is consistent with e.g. Linux's FUSE client, and allows
gofers to provide extended attributes from FUSE filesystems.
- Make tmpfs' listxattr omit xattrs in the "trusted" namespace for
non-privileged users.
