For the entropy analysis, we must provide some output from the Jitter RNG: a large amount of output from one instance, and a smaller amount of output from each of a certain number of instances. The original plan was to use a build of the userspace jitterentropy library that matches the kernel's jitterentropy_rng as closely as possible. However, it's now being requested that the output be gotten from the kernel instead. Now that fips140_lab_util depends on AF_ALG anyway, it's straightforward to dump output from jitterentropy_rng instances using AF_ALG. Therefore, add a command dump_jitterentropy which supports this.
