commit 081987b647 updated the Dockerfile
to disable go's telemetry in our dev / test-environment; as collecting
this data doesn't serve much purpose.
However, the configuration to disable telemetry is tied to the user's
home-directory (HOME); and disabling telemetry writs a config-file to the
user's home-directory (`~/.config/go/telemetry/mode`). While go provides
env-vars about the mode and location (`GOTELEMETRY` and `GOTELEMETRYDIR`),
those env-vars are read-only and cannot be used to either disable telemetry
or to set the location;
> Information about telemetry configuration is also available via read-only Go environment variables:
>
> go env GOTELEMETRY reports the telemetry mode.
> go env GOTELEMETRYDIR reports the directory holding telemetry configuration and data.
Some steps in our CI set up a different home-directory, which is not configured
to disable telemetry, which means that CI currently leaves behind a bunch of
files related to this;
make TEST_FILTER=TestPruneDontDeleteUsedDangling test-integration
tree -a bundles/test-integration/fake-HOME/
bundles/test-integration/fake-HOME/
└── .config
└── go

This patch disables go telemetry also for this home-directory to prevent
those files from being created, and to prevent go from producing the
telemetry.
With this patch, only the file to disable telemetry is produced:
make TEST_FILTER=TestPruneDontDeleteUsedDangling test-integration
tree -a bundles/test-integration/fake-HOME/
bundles/test-integration/fake-HOME/
└── .config
└── go
└── telemetry
