Add <sys/random.h>.

iOS 10 has <sys/random.h> with getentropy, glibc >= 2.25 has
<sys/random.h> with getentropy and getrandom. (glibc also pollutes
<unistd.h>, but that seems like a bad idea.)

Also, all supported devices now have kernels with the getrandom system
call.

We've had these available internally for a while, but it seems like the
time is ripe to expose them.

Bug: http://b/67014255
Test: ran tests
