build: fix build environment for the liveness test (cosmos#10551)

Extracted from cosmos#10210.

Make the test more reproducible, so that it does not require coordination
between the build container and the run container.

- Use layers to more advantage.
- Include bash in the run container.
- Put writable output onto a volume.
