Add exec_compatible_with to @go_sdk//:builder (#3943)
go_tool_binary() is completely oblivious of toolchains. The reason being
that Go toolchains actually depend on their output. Adding a toolchain
dependency would thus add a cyclic dependency. This is problematic,
because it means that the actions with mnemonic GoToolchainBinaryBuild
end up getting scheduled on arbitrary workers.
Address this by adding exec_compatible_with to the locations where
go_tool_binary() is instantiated, namely the auto-generated BUILD files
that are part of Go SDKs.
