requireVarDeclFirst rule doesn't recognize ES6 arrow functions provide a new function scope

[kfoisy]

When declaring a variable at the top of an ES6 arrow function, a new scope isn't recognized. The following code gives a "Variable declarations must be the first statements of a function scope." error, when it shouldn't:

() => { var something = 'test'; }

This behaviour is affecting also to requireMultipleVarDecl='onevar', as it says that the declarations should be joined.

@markelog Sad to see JSCS go away. Anyway sorry for being away for so long, I hope to get some time to look back here now that I am done with relocation. Are we still fixing issues that are open.

Works for me
