imgprod: Close .img before passing it to objcopy
This fixes a bug in the Windows port of newt.
Newt produces a .hex file by running `objcopy` on the .img file. It was
doing this immediately after creating the .img file, before closing it.
In Windows, objcopy cannot open a file when it is already open by a
different process, so the command fails.
The fix is to close the .img file before executing objcopy.
