LU-10886 build: fix WARNING: modpost: missing MODULE_LICENSE()

With newer kernels modpost will print a warning when no license is
provided. This could give false results if the kernel test set
the -Werror flag. Update LB_LANG_PROGRAM macro to include the
missing MODULE_LICENSE().

Test-Parameters: trivial
