vb21_common2_tests: Fix test for exponent 3 keys

vb2_public_key_read_keyb cannot be used for VB2.1 public keys
(especially not for 2048 exponent 3 or F4, as their size is the
same so the algorithm cannot be guess).

Instead, do what futility/rwsig does and derive the public key from
the private RSA key.
