Subject: [PATCH] daemon/selinux-relabel: don't exclude "/selinux" if it's
 non-existent

Since RHBZ#726528, filesystem.rpm doesn't include /selinux.  setfiles
then gives us the warning: "Can't stat exclude path "/sysroot/selinux",
No such file or directory - ignoring."

Though the warning is harmless, let's get rid of it by checking the
existence of /selinux directory.
