dosfstools: fix populated image creation with dirs

This fixes bug: [YOCTO #1783]

Fix populated image creation. Earlier subdirectories support
was broken, and files can only be placed in the root directory.
Now directory hirarchy is supported in the image. Also support
for long names is extended to directory names.

There are some outstanding issues as documented in the patch
header, these issues can be worked around by running
dosfsck tool after populated image creation. The dosfsck tool
is also part of this package.
