runtime, syscall: use the new get_random_bytes syscall for NaCl
The SecureRandom named service was removed in
https://codereview.chromium.org/550523002. And the new syscall
was introduced in https://codereview.chromium.org/537543003.
Accepting this will remove the support for older version of
sel_ldr. I've confirmed that both pepper_40 and current
pepper_canary have this syscall.
After this change, we need sel_ldr from pepper_39 or above to
work.
Fixes #9261
