Previously builds were done with Ubuntu 16.04, and now we are using
18.04. Thus the generated binaries will no longer work for
Ubuntu 16.04 and Debian 9 users, both of which are outside of their
support window and aren't supported by Abseil. RHEL users are
unaffected, as the binaries already didn't work on RHEL 7 and they will
remain working with RHEL 8. FWIW, Ubuntu 18.04 will leave its support
window in June.
* Added s390x platform support
* Adapt to existing platform naming scheme
* Updated s390_64 library whitelist
* Use g++ compiler version 8.x for s390x
* Introduced dedicated Docker container for building s390x artifacts Minor fix

CentOS 6 is dead and no longer has update servers. CentOS 7 is older
than Debian 9 (oldstable), so binaries hopefully work on both. More
testing is necessary, but everything's broken now, so this is better
than nothing.
We stop using protoc-artifacts because now the container is
straight-forward enough that we can just use our own. Previously the
"devtoolset" stuff made us want to share the container.
This mainly avoids protoc from 3.7.0 which has a dependency on libatomic. Most
of our systems have libatomic, so it mostly works, but the interop docker
container does not, so building fails. Version 3.7.1 was rebuilt to avoid
needing the libatomic shared library.
This has the added benefit that Bazel is now on the same version as Gradle, as
3.7.1 included fixes for Bazel.
The buildscript was updated to pull in a fix to protoc-artifacts to
support TLS 1.2 (google/protobuf#4879), which was the only remaining
reason to have our own container.
Docker container building was split out into a separate build_docker.sh
so that people can call it blindly and get the container necessary for
run_in_docker.sh.
