ar71xx: sysupgrade: accept ath79 combined-image

Browse Source 
There is md5 sum of whole image embedded in combined-image header which
is checked on sysupgrade. The check will fail for ath79 images which
may have embedded metadata. This is because metadata are appended after
the combined image is created. To allow smooth transition from ar71xx to
ath79, strip metadata before calculating md5 sum for whole image.
