scp: fix key length in dek_encrypt and dek_decrypt
When creating the DES cipher object with DES.new, we use the property
card_keys.dek. This property may hold a 16 byte key, but DES uses
an 8 byte key (56 bit + 8 bit integrity). Pycryptodome does not
automatically ignore excess key bytes. Instead it throws an
exception. This means we need to make sure to supply only the first
8 bytes of card_keys.dek
