Title: qemu.control.kernel-version: Bug fix for control.kernel-version

This patch fix three problems in control.kernel-version:
- Fix the wrong variable name.
- Remove the parse_file inside control file for host-kernel.cfg
Just in clude it as other cfg files in your tests-example.cfg
which is more flexible. And this also can work with the situation
that without host-kernel.cfg.
- Don't get the package version if there is no need for package
version check.

Also add some docstring for how to use the package filter.
