Modify EVP_CIPHER_is_a() and EVP_MD_is_a() to handle legacy methods too
These functions would only handle provided methods, but there are
cases where the caller just passes along a received method without
knowing the underlying method tech, so might pass along a legacy
method. We therefore need to have them handle this case as well so
they don't cause any unnecessary surprises.
