check /proc/filesystems before /proc/mounts for selinuxfs
Al was complaining that he has selinux disabled and has 100,000+ mounts
in /proc/mounts. Every time he runs ls the thing takes 5 seconds
because the libselinux constructor runs the entirety of his /proc/mounts
looking for selinuxfs, which doesn't exist. Speed things up by first
checking for selinuxfs in /proc/filesystems, only if the fs is even
registered should we bother to run all of /proc/mounts.
