    libsysprof-capture: Drop duplicate struct typedefs
    
    All three of these structs are already defined in
    `sysprof-capture-types.h`, which is included from these three headers.
    
    Drop the duplicate definition to silence the Clang warning:
    ```
    In file included from /opt/gnome/install/include/sysprof-4/sysprof-capture.h:63:
    /opt/gnome/install/include/sysprof-4/sysprof-capture-cursor.h:67:38: warning: redefinition of typedef 
'SysprofCaptureCursor' is a C11 feature [-Wtypedef-redefinition]
    typedef struct _SysprofCaptureCursor SysprofCaptureCursor;
                                         ^
    /opt/gnome/install/include/sysprof-4/sysprof-capture-types.h:98:41: note: previous definition is here
    typedef struct _SysprofCaptureCursor    SysprofCaptureCursor;
    ```
