Ignore deprecation warning about QSysInfo class

Amends 1bb4368a420ef12e3714bd4edfff34b8b3c983a8 .

QSysInfo is deprecated and replaced by the
QOperatingSystemVersion class which already exists.

Before Qt 6.0 is out, we can not remove these classes.
Fortunately, the warning can be suppressed by
setting QT_WARNING_DISABLE_DEPRECATED.

The options was already in the generated code, but the
placement was too late. The qsysinfo include happens
in the line

    // module include
    #include "pyside2_qtcore_python.h"

which comes right after the first "usePySideExtensions"
section.

Furthermore, the used template in headergenerator.cpp
needed the setting when the deprecated enum ocurred.
The section after

    "// Macros for type check"

got the setting, too, so that all calls to

    HeaderGenerator::writeSbkTypeFunction

were excluded from warnings.
