cmd/go: add an exception for 'go telemetry off' to not open counters
There is the expectation that if 'go telemetry off' is run with a clean
home directory that no counter files are written. But we were writing
counters in that case because the act of turning telemetry off was done
after the act of opening the counter files, so the counter files were
opened depending on what the previous mode was. Add a special check that
the command is not 'go telemetry off' before opening counter files.
Fixes #69269
