OSS-fuzz needs some love

With the attached obvious patch, the oss-fuzz build succeeds on their 
stock image. Haven't actually *ran* the fuzzer binaries though.

What do you suppose I should do on the oss-fuzz side? Do I just issue a 
pull request, or do I have to be listed somewhere?

Regarding drop of 16.04 build, we don't seem to have one in CI, so I can 
just remove the old Python exception. Do note however that oss-fuzz 
builds with clang, so we might want to have an Ubuntu 20.04+clang CI job 
to ensure that build doesn't fail when it gets to oss-fuzz.

I hope that helps,

Subject: [PATCH] fuzzing/oss-fuzz: fix image build recipe for Ubuntu 20.04

Update the build_image.sh script to install Ubuntu 20.04 packages
instead of Ubuntu 16.04 on the oss-fuzz container - this will
allow the oss-fuzz container to be based on Ubuntu 20.04.
