Add exfat-nofuse: EXFAT filesystem kernel driver

Add "exfat-nofuse" kernel module for EXFAT filesystem which was originally
found in an Android kernel of Samsung. While there has been some doubt about
the license originally, it has later been officially released under the GPL by
Samsung and can be found on:
