[Buildroot] [PATCH v3 1/6] package/go: implement go modules integration

[Christian Stewart <christian@paral.in>]

Hi all,

Was there any particular blocker / issue with this transition to Go
modules which needs addressing?

It should be fairly straightforward: this initial pass of the series
will allow the Go compiler to automatically resolve the "vendor"
directories rather than needing to build a symlinked GOPATH directory.
Everything that worked before should continue to work now, otherwise.

As reported on the Go release docs:

Module support in the go command is now ready for production use, and
we encourage all users to migrate to Go modules for dependency
management. If you are unable to migrate due to a problem in the Go
toolchain, please ensure that the problem has an open issue filed.

Best,
Christian Stewart
