Merge #17470: ci: Use clang-8 for fuzzing to run on aarch64 ci systems

fa2ec9f451 fuzz: Bump timeout in test_runner to accomodate for slow arm64 CPUs (MarcoFalke)
fa6e01b2f3 ci: Use clang-8 for fuzzing to run on aarch64 ci systems (MarcoFalke)

Pull request description:

  Ubuntu bionic clang is clang version 6, which does not come with libfuzzer. So the ci system breaks down when run on aarch64.

  Fix that by using clang-8

  For reference, the previous error on my ci system was:

  ```
  /usr/bin/ld: cannot find /usr/lib/llvm-6.0/lib/clang/6.0.0/lib/linux/libclang_rt.fuzzer-aarch64.a: No such file or directory
