What did you do?

1. Start with an empty home directory
2. go telemetry off
3. ls $HOME/.config/go/telemetry/local

What did you see happen?

I saw telemetry data in this directory:

'go@go1.23.0-go1.23.0-linux-amd64-2024-09-04.v1.count'	 upload.token   weekends

What did you expect to see?

I expected that this directory would be nonexistent since I have never before run a go command with this home directory, except for a command that expresses my desire to have telemetry disabled.

This wouldn't be an issue if telemetry could be disabled with an environment variable (#68960), and it would be less of an issue if telemetry data were written to a more appropriate location (#68988).

Once go telemetry clean is implemented, go telemetry off && go telemetry clean could do the job.
