Add AES-256 CFB to libdecrepit.

Electron builds Node.js with BoringSSL. They want to match OpenSSL as
much as possible and thus have a patch[1] that adds AES-256 CFB mode.
However, that patch makes libcrypto depend on libdecrepit, which can't
be done in general. This change lands the AES-256 CFB support in
libdecrepit without the libcrypto bit and, in order for BoringSSL to
remain consistent, without advertising support in
EVP_CIPHER_do_all_sorted. This will let Electron reduce the size of
their patch a bit.
