hugetlbfs: Implement show_options
Implement the show_options superblock op for hugetlbfs as part of a bid to get rid of s_options and generic_show_options() to make it easier to implement a context-based mount where the mount options can be passed individually over a file descriptor. Note that the uid and gid should possibly be displayed relative to the viewer's user namespace.
