Import upstream's tests for DES_ede3_cfb_encrypt
Upstream does not actually have any tests for DES-EDE3-CFB, with the
exception of a single DES-EDE3-CFB1 test vector, only the single-DES
version. But we can gain some coverage by turning 3DES back into single
DES with a repeated key. That's good enough for DES.
The DES-EDE3-CFB1 test vector is unusable because that tests
EVP_des_ede3_cfb1, the real DES-EDE3-CFB1. OpenSSL's low-level APIs do
not actually implement CFB correctly for a non-whole-number of bytes!
See discussion in the test. I've added coverage for that case by just
fabricating a test vector.
