stray files in go build / bob sandbox not empty

[Greg Troxel <gdt%lexort.com@localhost>]

I updated pkgsrc, did clean/scan/build and

  sandbox 3: Cannot remove sandbox: non-directory exists at /tank0/bob/3/home/gdt/.config/go/telemetry/local/link@go1.24.13-go1.24.13-netbsd-amd64-2026-07-09.v1.count

and it seems that there are multiple problems:

  go wants to do telemetry

  go is escaping FAKE_HOME set up by pkgsrc

  some combination of leftover files in home and bob objecting to
  polluted sandoxes


I have just been using rm -rf, but I wonder what the right path is.
