Makefile: Update the e2e target to use ginkgo (#2367)

Update the root Makefile and update the `e2e` target to use the ginkgo
executable instead of `go test ...` as logs produce when running the e2e
suite aren't captured until after the process has completed. This leads
to situations where failing tests aren't immediately communicated back
and loss of logs entirely in the case where the process was manually
teminated.
