Fix a compilation error on 32 bits architectures with gcc 14:

  ephyr_glamor_xv.c: In function ‘ephyr_glamor_xv_init’:
  ephyr_glamor_xv.c:154:31: error: assignment to ‘SetPortAttributeFuncPtr’ {aka ‘int (*)(struct _KdScreenInfo *, long unsigned int,  int,  void *)’} from incompatible pointer type ‘int (*)(KdScreenInfo *, Atom,  INT32,  void *)’ {aka ‘int (*)(struct _KdScreenInfo *, long unsigned int,  long int,  void *)’} [-Wincompatible-pointer-types]
    154 |     adaptor->SetPortAttribute = ephyr_glamor_xv_set_port_attribute;
        |                               ^
