libavb: Mark data const when calculating vbmeta hash

Update the signature of avb_slot_verify_data_calculate_vbmeta_digest()
to show that it only uses the AvbSlotVerifyData as an input. This lets
it be used when the client has a const pointer to AvbSlotVerifyData.

Test: atest --host --host-unit-test-only --test-mapping external/avb
