[meta-lts-mixins][scarthgap/go][PATCH 3/7] go: add ptest support

From: Pratik Farkase <[email protected]>

Add ptest infrastructure to test the Go standard library.

- Run 'go test -short std' via run-ptest script
- Install source tree and pkg/include headers
- Create VERSION file for architecture detection
- Exclude multi-arch binary testdata to avoid QA errors
