TOMOYO: Do not call tomoyo_realpath_init unless registered.
tomoyo_realpath_init() is unconditionally called by security_initcall(). But nobody will use realpath related functions if TOMOYO is not registered. So, let tomoyo_init() call tomoyo_realpath_init(). This patch saves 4KB of memory allocation if TOMOYO is not registered.
