futility: updater: decide if we can use diff-image by programmer

Previously we decide if the flash command can use the image_current as
the diff image by comparing if the target image pointer is identical to
the host image to write (cfg->image). This may not work properly if we
try to write a temporary firmware image object loaded separately.
A more correct way to is check if the image has the same programmer from
the diff image (e.g., image_current).

TEST=build and run futility tests.
