[PATCH] Documentation: Kunit: add MODULE_LICENSE to sample code

[Takashi Sakamoto <o-takashi@xxxxxxxxxxxxx>]

The sample code has Kconfig for tristate configuration. In the case, it
could be friendly to developers that the code has MODULE_LICENSE, since
the missing MODULE_LICENSE brings error to modpost when the code is built
as loadable kernel module.
