test: move test utils files to the test-utils folder

Tests that are currently on the main branch only runs against a qemu VM. We have other use cases that needs to be tested like running against a vfkit VM.
This commit reorganizes the tests code a bit by moving the files that can be shared to support different implementation in their own folder.
The reasoning behind this is that every hypervisor should have its own beforeSuite func to download/run a specific VM image. By moving the utils files we can reuse the same code.

For the same reason the code targeting qemu is moved to the test-qemu folder. By doing so, we can run the tests within the test-qemu folder on the ubuntu workflow and, in future, when the nested virt will be enabled on github runners, the vfkit tests on macOS.
