Ginkgo focus is not working on ./hack/test_e2e.sh script

[knabben]

Passing it as an env var is not read by the shell script, and the hardcoded one is always used: GINKGO_FOCUS='\[Conformance\]|\[sig-network\]'

For example:

 GINKGO_FOCUS="should resolve DNS of partial qualified names for services" bash -x ./hack/test_e2e.sh -i ipv4 -b iptables

GINKGO_FOCUS must read from an environment variable instead of using the hardcoded value.
