SQL/IBase: don't let open() fail when no timezones are available

Browse Source 
When connecting to an old Firebird instence with a Qt Firebird plugin
linked against Firebird >= 4 the timezone table is not available and
therefore open() will fail. Therefore downgrade the non-existence of
this table to a qCInfo().

Fixes: QTBUG-125467
