As Moritz says, the *config* is removed, because aes-ni is no longer a
*separate* module, it's built in to core openssl.

Note that the kernel module is not required for openssl, instead you
just need to verify that aes is in /proc/cpuinfo:

grep --color aes /proc/cpuinfo

(The aesni_intel kernel module gives you faster encrypted disks and
similar in-kernel cryptography systems.  The "aes cpuflag" ensures that
the AES-NI instructions are available to applications.)
