go: Add recipes for golang compilers and tools
* This is converging the recipes for go from
meta-virtualization and oe-meta-go
* Add recipes for go 1.7
* go.bbclass is added to ease out writing
recipes for go packages
* go-examples: Add an example, helloworld written in go
This should serve as temlate for writing go recipes
* Disable for musl, at least for now
* Disable for x32/ppc32 which is not supported
