[D3D] Enable creation of a zbuffer in system memory

[Christian Costa]

Hi,

Summoner wants to create a Z buffer with the DDSCAPS_SYSTEMMEMORY flag set.
This may looks strange but  this is so.
This  patch makes support  for this.
Now summoner works.

Changelog:
Enable creation of a zbuffer in system memory.
