Add arm64 support for the connectivity test

[aanm]

my assumption is that these scripts / manifests are not used in jenkins tests. If they are feel free to trigger them.

Just a message to report that with this commit, test do run on aarch64: I tested it on my RPi4 and it worked flawlessly.
Thanks for the quick fix 👏

They are, at least in the TProxy test and the Conformance tests:

cilium/test/k8sT/Policies.go

Lines 1771 to 1772 in 4d52791

	It("using connectivity-check to check datapath", func() {
	kubectl.ApplyDefault(connectivityCheckYml).ExpectSuccess("cannot install connectivity-check")

cilium/test/k8sT/Conformance.go

Lines 38 to 40 in 4d52791

	connectivityCheckYaml = kubectl.GetFilePath("../examples/kubernetes/connectivity-check/connectivity-check-hostport.yaml")
	connectivityCheckYamlQuarantine = kubectl.GetFilePath("../examples/kubernetes/connectivity-check/connectivity-check-quarantine.yaml")
	connectivityCheckYamlSimple = kubectl.GetFilePath("../examples/kubernetes/connectivity-check/connectivity-check-single-node.yaml")

test-me-please

@pchaigno It's not the first time I saw this in a different PR. I've opened #15922 to track it
