vfs_real: Fix MoveFile 

The file wasn't closed prior to being renamed / moved, throwing an error that states "The process cannot access the file because it is being used by another process." Fix this by closing the file prior to a rename / move operation.

Fixes saving in Luigi's Mansion 3 and KATANA KAMI: A Way of the Samurai Story.
