Remove test job in ci_linux.yml.

It was added in #199, in preparation for running GPU tests on non-GitHub
resources. But that seems unlikely to happen now, so it's just added
complexity and potential for unexplained failures (as seen in #332).
This commit removes it. We can always reinstate it if necessary.
