[PATCH v2] random: add proper SPDX header

[Jason A. Donenfeld]

Somehow this file missed the SPDXification efforts several years ago.
Convert the current license into "(GPL-2.0-or-later OR BSD-3-Clause)".

Hi SPDX List,

I think I got this conversion right, but I would certainly appreciate a
review on this from somebody with more legal expertise than me.

Thanks,
Jason
