ci: Make the skip list regexes match the full test name.

The bash scripts were using grep in the manner that matches any subset
of the line, but the new CTS runner matches the whole line and I think
that's a pretty good behavior.  Given that some of the skip lists
already were written to match the full test name, just make them
consistently do so.
