[go] Restrict go runtime to being fuchsia-only
This is step 3 of 3 of a restricting of the Golang Runtime to only
fuchsia binaries, as the last remaining host binaries are tests that
are also run on fuchsia.
This does the final visibility restriction change, so that the go
runtime is only available to fuchsia binaries.
