Subject: nixos/dd-agent: fix runtime errors by adding gohai to $PATH

The Datadog agent requires `gohai` to be available on its `$PATH` in
order to collect certain metrics.

It would previously start up and collect certain types of metrics, but
log errors related to the missing gohai binary.

This commit configures the systemd-unit to make gohai available at
runtime.

This fixes #39810.
