What companies actually manufacture the electric-shock units that
pet-containment system suppliers use on their collars.  Companies like
Innotek, D.T. Systems, PetSafe, and Tri-tronics sell collars for
training and containing dogs.  If they outsource the electronic module
that provides the electric shock, who do they buy this from?

I used to work at Innotek, so I can tell you that they do all their
own manufacturing, including the circuit boards. This way they have
control over such things as stimulation intensity and incremental
options (aka different stim level settings). They have a whole line of
engineers that develop these boards and do all sorts of quality
testing to make sure they meet electronic industry standards and such,
as well as of course ensuring that the circuit board does what it is
supposed to do without any complications.

As for the other manufacturers, I don't have any idea what processes
they use.
