ddraw: Don't set render target / depth stencil usage on sysmem surfaces.

Setting render target usage on a P8 surface for example would fail surface
creation, while such surfaces can't be used for actual rendering anyway. Tests
confirm that surface creation is supposed to succeed for P8 surfaces with both
DDSCAPS_SYSTEMMEMORY and DDSCAPS_3DDEVICE set.
