We had such an overloaded version in QSslSocket, it was deprecated without
providing any alternative. Now this function has some use and may be
introduced in Qt6, as QSslConfiguration::setCiphers(const QString &).
Last but not the least - a useless and strange auto-test was removed
(it was creating a list of 5 QSslCiphers each with isNull() == true).
That's becasue '!MD5' or 'ALL' (for example) is not a cipher to be found
in supportedCiphers.
