lib/sstatesig: Fix class inheritance problems

The locked sigs class needs to be inherited after the hashequiv mixin so
that get_unihash can correctly wrap the underlying hashequiv function.

To do this turn the locked sigs class into a second mixin, then the order
can be correctly handled. Tweak the get/set_taskdata to match.
