fdo#75540 setProcessServiceFactory must be called before InitVCL

...because InitVCL now calls:

> comphelper::getProcessServiceFactory
> comphelper::getProcessComponentContext
> utl::DefaultFontConfiguration::DefaultFontConfiguration
> rtl::Static<utl::DefaultFontConfiguration, (anonymous namespace)::theDefaultFontConfiguration>::get
> utl::DefaultFontConfiguration::get
> ImplStyleData::SetStandardStyles
> ImplStyleData::ImplStyleData
> boost::make_shared<ImplStyleData>
> StyleSettings::StyleSettings
> ImplAllSettingsData::ImplAllSettingsData
> boost::make_shared<ImplAllSettingsData>
> AllSettings::AllSettings
> Application::InitSettings
> Application::GetSettings
> GtkInstance::AfterAppInit
> InitVCL
> ImplSVMain
> SVMain
> sal_main
> main

and Application::Main is only called after InitVCL.
