[PATCH v2] selinux: clean up dead code after removing runtime disable

[Lukas Bulwahn <lukas.bulwahn@gmail.com>]

Commit f22f9aaf6c3d ("selinux: remove the runtime disable functionality")
removes the config SECURITY_SELINUX_DISABLE. This results in some dead code
in lsm_hooks.h.

Remove this dead code.
