fs/fat/fat_write: Fix management of empty files
Overwriting an empty file not created by U-Boot did not work, and it could even corrupt the FAT. Moreover, creating empty files or emptying existing files allocated a cluster, which is not standard. Fix this by always keeping empty files clusterless as specified by Microsoft (the start cluster must be set to 0 in the directory entry in that case), and by supporting overwriting such files.
