fix(ci): resolve lint, test, and build failures from refactor

- Fix goconst: extract repeated test string literals into constants
  in internal/plumbing/intf/intf_test.go
- Fix gofmt: correct import ordering in internal/cni/cni.go and
  internal/cni/veth/veth.go
- Fix lll: wrap long flag description lines in cmd/galactic-agent/main.go
- Fix Dockerfile: remove stale COPY pkg/ pkg/ (pkg/ was deleted)
- Fix ci.sh: gate kernel module install on GITHUB_ACTIONS=true so
  task test:e2e works locally without sudo apt-get
- Fix Taskfile yaml-ext: exclude deploy/containerlab/clab-gvpc/ from
  .yml extension check
