Puma::Launcher: avoid a leading space character in RUBYOPT (#1455)

Browse source 
The problem is this:

```
2.4.2 :001 > [nil, 'foo'].join(' ')
 => " foo"
```

Note the leading space character. By `lstrip`:ing the result of the join, we avoid this altogether.

(This is a fix for the underlying problem that triggered https://github.com/jruby/jruby/issues/4849.)
