This fixes mirage#94, since register_source is called only once for the rdrand task.

@EduardoRFS as I don't understand esy too well, could you briefly look into the cross-compilation CI failure? to me it looks that it tries to build with a released / master version, and fails since the interface changed... |

@hannesm feel free to merge, I will fix it in a couple of hours, this CI style isn't great |

…age-crypto-rng-mirage and mirage-crypto-rng-async (0.8.8) CHANGES: - new package mirage-crypto-rng-async, entropy feeding using async (mirage/mirage-crypto#90 @seliopou) - Entropy.cpu_rng and Entropy.cpu_rng_bootstrap result in Error `Not_supported on CPUs without RDRAND/RDSEED support (previously an exception was raised in cpu_rng_bootstrap, and cpu_rng resulted in a no-op) (mirage/mirage-crypto#92 @seliopou) - Entropy.cpu_rng delays entropy feeding (returns unit -> unit instead of unit). This fixes a memory leak, reported by @talex5 mirage/mirage-crypto#94, fixed in mirage/mirage-crypto#95 by @hannesm - Avoid illegal instructions on X86 CPUs without SSSE3 instruction set. Both SHA256 and ChaCha used PSHUFB which is not available on e.g. AMD Phenom II (report mirage/mirage-crypto#93 by @dinosaure @samoht @pirbo @RichAyotte @sebeec, fixed in mirage/mirage-crypto#96 by @hannesm)
