Upload: Add a MIME type exception for .docx generated by Google Docs.

Browse Source 
This changeset adds an exception to prevent permission issues on `.docx` generated by Google Docs. This is a temporary fix for an upstream bug on the `finfo_file()` 
PHP function which returns a redundant MIME type for these documents.
