Having an rng in the sandbox is useful not only for tests but also for e.g. UEFI. Therefore, copy the rng node from test.dts to sandbox.dtsi.
In the case of UEFI, it can then be verified with `efidebug dh' that a "Random Number Generator" protocol is indeed present.
This also fixes the following `bootefi' error:
The message is written with log_warning(). It is not an error.
An error is written in the lib/efi_selftest/efi_selftest_rng.c when executing the unit test.
Please, remember that this is not a good PRNG. If you want proper random values, you would have to change the driver to use the host's getentropy() function.
