QSslCipher - improve its code coverage and auto-tests

tst_qsslcipher was quite useless - now we test that default constructed
QSslCipher reports expected values. Test the non-default from the
different auto-test,  where we are sure we have really useful
ciphersuites (with different parameters obtained from a TLS backend,
where it's possible).
