assigns ISO_Level3_Shift as VK_RMENU in X11DRV_InitKeyboard

On Ubuntu 8.04, the right alt key generates ISO_Level3_Shift (keysym ==
0xfe03), which wine doesn't currently recognize as the right alt button. Found
the problem while playing World of Warcraft, where I wasn't able to use the
right alt key to trigger actions mapped to a combination of alt and another
button.

The attached patch changes X11DRV_InitKeyboard to handle ISO_Level3_Shift as
VK_RMENU. This solves the problem for me, but I don't know if it's the proper
way to handle this bug.
