distro: default: Change Go default version to 1.9

Source: poky
MR: 00000
Type: Integration
Disposition: Merged from poky
ChangeID: f6d8c3f
Description:

For the time being, there is a serious bug[1] in Go 1.10 when it comes to
use the shared runtime support which cases problems in multiple projects.

 1. golang/go#24640

It is still unclear if the problem arises from a bug inside the
compiler itself or it makes a real problem more visible. Either way,
using 1.10 as default seems to be a risk so we are changing back to
1.9 for now.
