Problem: It is noticed that below MTR tests uses individual encryption_mode checks in
the test.

func_aes_cfb1.test
func_aes_cfb128.test
func_aes_cfb8.test
func_aes_ofb.test

However the above encryption_mode CFB1, CFB8, CFB128, OFB are only supported
by OpenSSL.The aim of this Bug fix is to remove the skips from the test and
include have_openssl.inc

Fix: Added have_openssl.inc in the tests and removed individual encryption_mode checks.
