Hide macOS system files in the root of the SD card (#113)

<!--- Provide a general summary of your changes in the Title above -->

## Description
Make the root of the SD card a little cleaner by hiding the crap that
macOS puts there.

## Motivation and Context
Whenever an SD card touches macOS, a handful of hidden files get created
that cannot be touched. N64FlashcartMenu has no need for these files, so
they should be hidden.
