Emmanuel Gil Peyrot 4c212a1168 util/rand_xor: use getrandom() when available 
This function has been added in glibc 2.25, and the related syscall in
Linux 3.17, in order to avoid requiring the /dev/urandom to exist, and
doing the open()/read()/close() dance on it.

We pass GRND_NONBLOCK so that it doesn’t block if not enough entropy has
been gathered to initialise the /dev/urandom source, and fallback to the
next source in any error case.
