gsdx: add CRC hack for Nocturne PAL 

Reduce depth transfer to the real size of the game. Otherwise
we need to handle a mix of color/depth transfer.

/*
* The game uses a resolution of 512x244. RT is located at 0x700 and depth at 0x0
*
* #Bug number 1. (bad top bar)
* The game saves the depth buffer in the EE but with a resolution of
* 512x255. So it is ending to 0x7F8, ouch it saves the top of the RT too.
*
* #Bug number 2. (darker screen)
* The game will restore the previously saved buffer at position 0x0 to
* 0x7F8. Because of the extra RT pixels, GSdx will partialy invalidate
* the texture located at 0x700. Next access will generate a cache miss
*
* The no-solution: instead to handle garbage (aka RT) at the end of the
* depth buffer. Let's reduce the size of the transfer
