lib: handle one of args case in ERR_MISSING_ARGS
Browse files Browse the repository at this point in the history
This makes ERR_MISSING_ARGS handle nested arrays in argument names as
one-of case and will print them as '"arg1" or "arg2" or "arg3"'.

Example:
```js
throw new ERR_MISSING_ARGS(['a', 'b', 'c']);
// will result in message:
// The "a" or "b" or "c" argument must be specified
```
