Dockerfile: upgrade to Ubuntu 24.04

Switch to Ubuntu 24.04, bump some
versions of dependencies, and use
some of the packages from Ubuntu
instead of building OpenCV manually.

There is also an ubuntu user/group
by default in the base image, so
use that instead of creating
a separate docker user like before.
