Changes since v1:
  * Build crypto-obj-y for linux-user as well.
  * Several patches to tidy crypto/random-platform.c.
  * Use getrandom(2) in crypto/random-platform.c.
  * Use qcrypto_random_bytes in ui/vnc.c.
  * In qemu_getrandom:
    - Use g_rand_int instead of srand48.
    - Use qcrypto_random_bytes instead of getrandom directly.
