Fix build error due to forward enum declaration

In full build, the following error happens. So fix it by including the
definition file before the forward declaration one.

```
In file included from source/blender/io/collada/SkinInfo.cpp:40:
source/blender/blenkernel/BKE_object_deform.h:62:6: error:
 enumeration previously declared with nonfixed underlying type
enum eVGroupSelect
     ^
In file included from source/blender/io/collada/SkinInfo.cpp:36:
source/blender/makesdna/DNA_scene_types.h:2099:14: note:
previous declaration is here
typedef enum eVGroupSelect {
             ^
1 error generated.
```
