testing/kubernetes: upgrade to 1.12.2

- Change URL to HTTPS.
- Change license to SPDX format.
- Change source back to GitHub, dropping custom 'unpack()' method.
- Add 'ensure-cgo-usage.patch'.
- Drop 'fix-support-for-ppc64le.patch' as the package isn't built for
this architecture.
- Enable verbose build to avoid timeout on Travis CI.
- Sort binaries list, drop 'kube-aggregator' that was removed upstream
and use 'local' variable declaration.

+Subject: [PATCH] Ensure CGO usage
+
+There are checks to define if CGO is required by the platform, but those
+are not enough to ensure its usage in Alpine. This leads to errors like:
