Add two tests which verify that encrypted files are encrypted correctly
when a hardware-wrapped inline encryption key is used.  The two tests
are identical except that one uses FSCRYPT_POLICY_FLAG_IV_INO_LBLK_64
and the other uses FSCRYPT_POLICY_FLAG_IV_INO_LBLK_32.  These cover both
of the settings where hardware-wrapped keys may be used.
