Subject: [PATCH] nixos/grafana-agent: use `lib.getExe` as binary names changed
 between updates

and `lib.getExe` allows a safe handling and potential backport of this.
But for that to work it would require 22.11 to set `pkgs.grafana-agent.meta.mainProgram = "agent"`

Relevant upstream release: https://github.com/grafana/agent/releases/tag/v0.31.0
