Fix error in local-cluster-up

When $GO_OUT is not set, line 152 outputs an error.

```
./hack/local-up-cluster.sh: line 152: [: ==: unary operator expected
```
This occurs because the if condition expands as `if [  == "" ]`. This results in an error because == is a binary operator and expects something on the LHS.

**Release note**:

```release-note
NONE
```
