Description of changes:
Looks like something in last week's kissat release is causing one or more of our CBMC proofs to hang indefinitely: https://github.com/arminbiere/kissat/releases/tag/rel-4.0.4
For now, pin to the last release.
Call-outs:
I notice we have a couple other CBMC dependencies in there pinned. We probably need to do some cleanup.
Testing:
CBMC job now succeeds.
