[PATCH] CI: Remove llvm-8 from the Debian Stretch container

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

For similar reasons to c/s a6b1e2b80fe20.  While this container is still
build-able, all the other problems with explicitly-versioned compilers remain.

This will require backporting to older trees, but there's already a list it
can be added too.
