fix: keep the platform's hash order when unchanged

Where the truth names no value the platform lacks, hashes() still put
the truth's values first and rewrote the list in another order:
Recalbox's msx/CARTS.SHA md5 attribute came out with its two values
swapped, a diff line that changes nothing the frontend checks. The
platform's own list now stands when it already holds every value.
