Fix incorrect default keysize for CAST ofb and cfb modes.
Fixes #11459
It was incorrectly using 8 bytes instead of 16 as the default.
This was verified by expanding the macros used in e_cast.c.
The issue occurs if EVP_CIPHER_CTX_set_key_length() is not called.
evp_test.c hides this issue as it always calls EVP_CIPHER_CTX_set_key_length() before
using EVP_CipherInit_ex(...., key, ..).
