All cipher suite names supplied through --tls-cipher are translated by
OpenVPN to IANA names, to get OpenSSL and PolarSSL configuration files
compatible. OpenSSL however supports cipher suite group names, like
'DEFAULT', 'HIGH', or 'ECDH'. To make OpenVPN not complain about these,
entries translating these to themselves were added to the translation
table. However, to make OpenVPN not still complain, the deprecated-name
check has to be reversed from 'if this is a deprecated name then complain'
to 'if this is not a iana name, then complain'. Which this commit does.
