uxtheme: Call DefDlgProc() if drawing tab body in a dialog fails. 

Some third party themes have tab body part defined but with its ImageSelectType set to IST_NONE.
In this case, DrawThemeBackground() will fail to draw the background.

Fix track bar black background in winecfg when using VLT theme.
