Peter Johnson b45572167d [build] Change CI back to 18.04 docker images (#3456) ...

This reverts commit d068fb321f (#3420).

The 18.04 docker images now use GCC 8, which was the original reason for
updating.  20.04 uses a much more recent libc, so staying with 18.04
enables more Linux platforms to use the binaries.
