Make QCoreApplication::applicationName() default to argv[0]

This makes it more useful in all the Qt apps that don't set it,
given that it's used internally by QTemporaryFile, QTemporaryDir,
QStandardPaths, QDBus, QAccessibleApplication, etc.

Qt4 compatibility in the deprecated QDesktopServices is preserved,
no fallback there.
