modules/sparkler: s/rand/rand_r/ and wire up seed
This is a little contorted but not too bad. The input to
particles_new() is just a const conf struct, so instead of
passing in the seed value for particles_t to contain, a pointer
to where the seed lives is passed in via the conf. This requires
the caller to persist a seed somewhere outside the particles
instance, but at least in rototiller we already have that
conveniently in til_module_context_t.
