Subject: [PATCH] CI: Build on Ubuntu 18.04, use newer clang-format

There are too many issues with 20.04 to successfully build with
VirtualCam - the azure kernel is missing videodev headers. For now,
use 18.04 LTS directly for main CI builds.

Both 18.04 and 20.04 include clang-format-10 without issue.
