Adrian Reber bb98a9cd2f Fix podman port -l ...

Running 'podman port -l' on a system without any containers created
gives:

 $ podman port -l
 panic: runtime error: invalid memory address or nil pointer dereference
 [signal SIGSEGV: segmentation violation code=0x1 addr=0x10 pc=0xf3cef1]

 goroutine 1 [running]:
 github.com/containers/libpod/libpod.(*Container).State(0x0, 0x0, 0x0, 0x0)
 	/share/go/src/github.com/containers/libpod/libpod/container.go:658 +0x41
 main.portCmd(0xc420094580, 0x0, 0x0)
 	/share/go/src/github.com/containers/libpod/cmd/podman/port.go:118 +0x406

This fixes it by making sure the variable 'containers' is nil and not [<nil>].
