unit-tests: Invoke unit tests using go test directly instead of ginkg…

…o cli (#3104)

Saves having to install the gingko cli for unit tests.
Additionally, this brings HCO more in line with how the kubevirt/cdi invokes
unit-tests with go.
Lastly invoking the tests with ginkgo on s390x causes it to randomly hang
forever.
