9e111db088e4137865ae068d206c769994ea0a29 test: set a name for CI Docker containers (fanquake)
Pull request description:
Addresses one part of #16664, by making it easier to identify CI containers that are running locally. By default Docker will generate random names, like `peaceful_rubin`, with this change, we explicitly set names for all containers.

ef63f5fc1136ad2a2cd080d44142a2ee3945c238 ci: Combine 32-bit build with CentOS 7 build (Sebastian Falbesoner)
Pull request description:
Combines the CentOS build with the 32-bit (i686) build to avoid Travis bottlenecks, as suggested in #17757 by MarcoFalke. This keeps most of the properties of the 32-bit build (dash as config shell, building QT5 GUI) and just builds it with depends inside the CentOS docker container.
Making the depends in `05_before_script.sh` with unset config shell (`CONFIG_SHELL=`)
6196e93001/ci/test/05_before_script.sh (L28)
caused problems for building the library libevent (resulting in a Makefile with no shell set (`SHELL=`)), that's why I set it explicitely to `/bin/bash` if we have a CentOS Docker container.
A Travis output of this 32-bit CentOS build can be seen here: https://travis-ci.org/theStack/bitcoin/jobs/634472394 (has been restarted once due to too long build time and appearance of the `CACHE_ERR_MSG`).
For anyone wanting to verify the outputs, I found these instructions useful to reproduce a Travis build locally: https://github.com/erdc/proteus/wiki/Replicating-the-TravisCI-Environment-on-your-Local-Machine (steps 1-3). In this case it's a bit tricky since you run Docker inside Docker -- within the Travis Docker container, the CentOS Docker container is created. To make this possible, the Docker socket has to be exposed to the Travis container via bind-mounting (`docker run -v /var/run/docker.sock:/var/run/docker.sock ...`), as suggested in https://stackoverflow.com/a/33003273.
