socket: Use AES128 cipher in SSL if AES is supported by CPU
SSL performance is improved after configuring AES128 cipher so use AES128 cipher as a default cipher on the CPU those enabled AES bits otherwise ssl use AES256 cipher Change-Id: I91c50fe987cbb22ed76f8012094730c592c63506 Fixes: #1050 Signed-off-by: Mohit Agrawal <moagrawal@redhat.com>
