Victor Stinner 035ba5da3e Issue #29157: Prefer getrandom() over getentropy() 
Copy and then adapt Python/random.c from default branch. Difference between 3.5
and default branches:

* Python 3.5 only uses getrandom() in non-blocking mode: flags=GRND_NONBLOCK
* If getrandom() fails with EAGAIN: py_getrandom() immediately fails and
  remembers that getrandom() doesn't work.
* Python 3.5 has no _PyOS_URandomNonblock() function: _PyOS_URandom()
  works in non-blocking mode on Python 3.5
