Speed up DiffusionBrowseFileController by removing call to array_merge
Summary: Some profiling using XHProf in the Dark Console showed me that Diffusion was wasting a ton of time on array_merge. This change sped up the loading of a large file in Diffusion from 16.8 seconds to 2.4 seconds.
Test Plan: Load files in Diffusion. They all look good. Also, use a PHP shell to try to manually verify that I still kinda remember some PHP and, yes, this is functionally equivalent to what was there before.
