dosfstools: Add patch to disable fat32 autoselection and behave as 2.10

It appears msdos image population and fat32 images are incompatible.
This reverts to the 2.10 behaviour of defaulting to fat16 instead of
using fat32 for large images, allowing image generation to work
correctly. This is a workaround and a proper fix is really needed.

+FAT32 appears to be broken when used with the -d option to populate the msdos
+image. This disables the FAT32 autoselection code which means we don't get
+broken images with the -d option. It can still be enabled on the commandline
+at the users own risk. This changes us back to the 2.10 version's behaviour
+which was known to work well even with large images.
