ci: Use a container and expand versions

Use containers to build/test so it's not restricted to the OS versions
supported by Github runners. A few changes are needed to the workflow to
support using containers:

	1) No need for sudo, so remove it
	2) Explicitly install missing zlib
	3) Explicitly pass KDIR= while building kernel modules, since it
	   won't match `uname -r`. This assumes the container has just
	   one kernel installed and so /usr/lib/modules/*/build can be
	   used as the single symlink to the kernel headers. This should
	   be common to other distros to be added, too.
