apply: use COPY_ARRAY and MOVE_ARRAY in update_image()

Simplify the code by using the helper macros COPY_ARRAY and MOVE_ARRAY,
which also makes them more robust in the case we copy or move no lines,
as they allow using NULL points in that case, while memcpy(3) and
memmove(3) don't.

Found with Clang's UBSan.
