[wic][PATCH] wic: bootimg_efi: fix debug output for mkdosfs

Set the copy output correctly when making the filesystem in order for
the debug log line to correctly show the made filesystem.

See commits dea8d761712 ("wic: bootimg_efi: fix debug output for
part.include_path") and 5643596fd76 ("wic bootimg-efi.py: keep
timestamps and add debug prints")
