SELINUX: add /sys/fs/selinux mount point to put selinuxfs
In the interest of keeping userspace from having to create new root
filesystems all the time, let's follow the lead of the other in-kernel
filesystems and provide a proper mount point for it in sysfs.
For selinuxfs, this mount point should be in /sys/fs/selinux/
