[Bug]: configure: Go extension uses host Go SDK

[alexeagle]

What happened?

Somewhere in the code for the Go gazelle extension it wants to shell out to a go subprocess. When used via aspect configure rather than a gazelle_binary target, this leaks out to using a Go SDK installed on the system.

Version

HEAD

How to reproduce

No response

Any other information?

We should figure out why the extension wants to call a subprocess. This is against our design for making it a standalone tool.

I don't think we actually plan to fix this, instead we'll write our extensions in pure starlark.
