kinetis: save 'wdog-disable.bin' binary in the repository

Keep the compiled '.bin' file to remove the need to compile it when
flashing. This remove the need to have the toolchain when flashing so
allow compiling and flashing with `BUILD_IN_DOCKER=1` without a local
toolchain.

Even if it ends up storing a binary, the file is only 34 bytes.
