cbfstool: Fix cbfs_copy_instance()'s master header endianness
The function hadn't been updated to account for the fact that we now
copy an endianness-corrected CBFS master header into a separate buffer
from the CBFS data: it still performed pointer arithmetic accross the
two buffers and wrote the copied buffer into the image without
restoring the original endianness.
