    scan: set title also when the class structure is opaque
    
    libnm doesn't like to include the structure definitions of many object
    types in a public header, since they're not supposed to be subclassed
    and maintaining a stable ABI would me a maintanance burden:
    
    nm-setting-user.c: struct _NMSettingUserClass { ... };
    nm-setting-user.h: typedef struct _NMSettingUserClass NMSettingUserClass;
    
    However, gtkdoc-scan only sets <TITLE> for Class/Iface typedefs only when the
    structs are defined in the header. Fix that.
