bgpd: Do not print new line for EVPN CLI outputs if it's a JSON

Before:

```
$ vtysh -c 'show bgp l2vpn evpn route detail json'
<<<<<<<<<<<<<<<<<<<< empty line
<<<<<<<<<<<<<<<<<<<< empty line
<<<<<<<<<<<<<<<<<<<< empty line
<<<<<<<<<<<<<<<<<<<< empty line
{
	...
	"numPrefix":4,
	"numPaths":4 <<<<< four paths = four empty lines
}
```

Contain as much "empty lines" before the JSON string as the number
of paths displayed.
