[issue27266] Always use getrandom() in os.random() on Linux and add block=False parameter to os.urandom()

I don't think that happens.

getrandom() actually supports two flags.  The flag GRND_RANDOM tells it "behave like /dev/random".  If you don't pass in GRND_RANDOM, it behaves like "/dev/urandom".  So it's hard to imagine that you could have getrandom() and not have /dev/urandom.
