go_1_16: init at 1.16

Changes are minor - I ended up just patching the ssl certs at the root
file, rather than trying to keep up with the various darwin changes.

The externalnetwork test helper location changed, to so I had to update
that patch as well.

- Add xcbuild as propagatedBuildInput on darwin https://github.com/golang/go/commit/7e25bdba5e79d223566745fca2410f725a6dedda

+Starting from go1.14, go verifes that vendor/modules.txt matches the requirements
+and replacements listed in the main module go.mod file, and it is a hard failure if
+vendor/modules.txt is missing.
+
+Relax module consistency checks and switch back to pre go1.14 behaviour if
+vendor/modules.txt is missing regardless of go version requirement in go.mod.
