Makefile: Drop find-godeps.sh for podman target

We inherited this from a031b83a (Initial checkin from CRI-O repo,
2017-11-01), but:

* The output is actually going into bin/podman, so Make will rebuild
  this target every time.  You'll never be able to save compilation
  because the target is newer than all the prerequisites.

* Make expands prerequisites immediately when loading a Makefile [1],
  and on my wimpy Chromebook SD Card, this is *slow*:

    $ time hack/find-godeps.sh ~/.local/lib/go/src/github.com/projectatomic/libpod cmd/podman github.com/projectatomic/libpod
    ...
    real    0m56.225s
    user    0m44.918s
    sys     0m21.918s

* Go is pretty good at this on its own, so having make call 'go build'
  every time will almost certainly be faster than us trying to mimic
  this in a shell script.  And by punting to Go in the recipe, Make
  invocations that do not need the podman target (e.g. 'make help')
  can skip the dependency lookup entirely.
