Kernel/FileSystem: Fix handling of FAT names that don't fill an entry

Browse source 
* Fix bug where last character of a filename or extension would be
   truncated (HELLO.TXT -> HELL.TX).
 * Fix bug where additional NULL characters would be added to long
   filenames that did not completely fill one of the Long Filename Entry
   character fields.
