firmware-utils: mkmylofw: fix blocks padding
The old code didn't make sense as it was using "len" variable which was
guaranteed to be always 0. Loop right above broken code is:
while (len > 0) { }
With this recent ALIGN macro fix this resulted in subtracting block size
from 0 and calling write_out_padding() with a negative length.
To calculate amount of bytes needed for padding & alignment it should be
enough to use % 4.
