test: Use new test-verifier image in K8sVerifier

Until now, K8sVerifier was using the cilium-builder image to build the
datapath and run verifier-test.sh. Having a K8sVerifier-specific image
also allows us to include a patch for the tc binary, to increase the
maximum size of the verifier log buffer. In the K8sVerifier test, we
load all BPF programs in verbose mode, so the log buffer is always
needed (vs. only in case of retry following a load error usually). A
small log buffer can lead to a load failure that is actually a false
positive (it's just the log buffer being too small and not an actual
issue with the BPF program).
