Similar to what is already done with DISTRO, which points to given image
of ours based on name. This time we do the same with upstream images,
such as debian:stretch or centos:centos8.
This way, for instance calling docker_images_require
"osmo-bsc-latest-centos8" would try to build the
osmo-bsc-latest/Dockerfile file starting from a centos8 image.

Since we'll now log the script and its children output to a file, let's
make sure the loop doesn't run countless times upon failing child
process, producing lots of potential undesired output. For instance, if
osmo-bts fails to read vty config and exits immediately.

This will enable us to run the PCU testsuite automatically by
jenkins, just like for other Osmocom projects.
