If an image creates a rootfs which is exactly a multiple of 64 MByte then
the scripts never detects that the last chunk has been read and
'run update' never completes.
Fix that by explicitely setting filesize to 0 when a file read fails.

Our current update procedure reads the rootfs payload in pre
split files of 64 MB size. However due to the workaround for
u-boot counting in hex and split did in decimal, the number of
chunks is limited to 89 resulting in a maximum size of 5.5GB.
Update the u-boot counting procedure to count in 3 digits from
the current 2 digits. This allows more than 800 plus chunks
which should take care of rootfs size and any future eMMC
update requirements.

Our current update procedure requires the rootfs payload to fit in
one file on a FAT filesystem. This limits its usable size to 4GB.
Use the process of splitting up the files in 64MB chunks and then
doing the update which is also what the Ethernet update scripts
currently follow.
However due to the workaround for u-boot counting in hex and split
did in decimal, the number of chunks is limited to 89 resulting in
a maximum size of 5.5GB. We will remove the limitation in a follow
up patch.

This requires to adjust the path to include files, e.g.:
-require recipes/images/trdx-image-fstype.inc
+require recipes-images/images/trdx-image-fstype.inc
