Add a test to check and see if RANDOM-STATE builds cleanly

[rpgoldman]

Check to make sure that random-state builds w/o warnings on a wide variety of systems.

Interestingly, while this test passes for me locally, it fails when run as a GitHub action, with redefinition warnings on all lisps. Not sure why this is happening. @Shinmera any clue?

Failed to build cleanly: got STYLE-WARNINGs:
