Fix a compatibility issue with ArcanistUnsafeDynamicStringXHPASTLinterRule

Browse source 
Summary: A user reported to me that `arc lint` was failing with an error message along the lines of "argument 1 passed to `idx` must be of type array, bool given". I suspect that the user is running an older version of PHP, which means that `array_combine(array(), array())` is returning `false` instead of the expected `array()`. Instead, avoid calling `array_combine` on an empty array.

Test Plan: I don't have PHP 5.3 easily accessible to test this.
