jenkins-common: add NO_DOCKER_IMAGE_PULL
The docker_images_require function runs "docker build" with the "--pull"
argument to automatically get new base images (typically debian
bookworm).
Recently this started to cause an error when building the arm32/v7
image debian-bookworm-build-arm on the now arm64/v8 (aarch64) rpi4.
Add NO_DOCKER_IMAGE_PULL to be able to omit "--pull". The related patch
adjusts osmo-ci to pull separately beforehand.
