[Buildroot] [git commit branch/next] package/go: introduce HOST_GO_COMMON_ENV

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=557282a9c046547daade72fe18e233006716d0b2
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

A few variables are common between HOST_GO_TARGET_ENV and
HOST_GO_HOST_ENV, so let's introduce a HOST_GO_COMMON_ENV variable for
those few common ones (which will increase in follow-up commits).
