Add aliases for des-ede-ecb and des-ede3-ecb ciphers.

Currently we can get all block ciphers with
	EVP_get_cipherbyname("<alg_name>-<block-mode-name>")
for example, by names "aes-128-ecb" or "des-ede-cbc".
I found a problem with des-ede-ecb and des-ede3-ecb ciphers as
they can be accessed only with names:
	EVP_get_cipherbyname("des-ede")
	EVP_get_cipherbyname("des-ede3")
It breaks the general concept.

In this patch I add aliases which allow to use names:
	EVP_get_cipherbyname("des-ede-ecb")
	EVP_get_cipherbyname("des-ede3-ecb")
in addition to the currently used names.
