workflows/e2e: Use fluxcd/pkg/actions/envtest

Use fluxcd/pkg/actions/envtest to setup envtest.

Since the run-test action runs in a container, the host $PATH is not
passed to the test container. The ENV directive in actions/run-tests
Dockerfile is used to append the PATH with envtest binary path. This
helps avoid redownload of the envtest binaries when it's not found in
the path via the Makefile targets.
