random: ignore GRND_RANDOM in getentropy(2)
commit 48446f198f9adcb499b30332488dfd5bc3f176f6 upstream.
The separate blocking pool is going away. Start by ignoring
GRND_RANDOM in getentropy(2).
This should not materially break any API. Any code that worked
without this change should work at least as well with this change.
