Fix libfsimage build on NetBSD.

Fixes a number of these errors:
 cc1: warnings being treated as errors
 fsys_fat.c: In function 'fat_dir':
 fsys_fat.c:304: warning: array subscript has type 'char'

Signed-off-by: Christoph Egger <Christoph.Egger@amd.com>

These ugly casts are needed according to the ISO C spec.
