Correctly fail in build-script

If a container image failed to build, the build-script did not always
report this. This was the case, if multiple images were built at the
same time and happened because a global variable was used to track
failures, which was not correctly reset between builds.

This change changes the method to detect return codes of the docker
build command, to detect build failures more consistently.

The success of `docker build`-commands is also tested in other parts of
the script. To stay consistent in how the success of the build is
determined, these instances were adapted accordingly, although these
were functioning as intended, since only one image was build at a time
for these cases.
