grafana-agent: 0.21.2 -> 0.24.1 (#169558)

We can skip our little patch. The file was removed in
https://github.com/grafana/agent/pull/1362, which includes
https://github.com/grafana/agent/pull/1268.

The condition to exempt network tests was inverted as part of these PRs,
so we now need to set GOFLAGS explicitly to exclude tests that can't run
inside the Nix sandbox.
