modules/mixer: restrict randomized module settings

This is mainly to prevent the mixer's b_module=compose default
from always sending the randomizer down a deep nested compose
scenario.

But it's also just giving the mixer random variety in both a/b
modules, while keeping compose out.

This alone seems to go a long way towards preventing
problematically deep randomized setups under rtv.
