egl/x11: Fix initialisation of swap_interval

Browse source 
The EGLConfig attributes EGL_MIN/MAX_SWAP_INTERVAL were incorrectly set to
0 and 0. This prevented clients from setting the swap interval to a
reasonable value, like 1 or 2.

Swap interval worked correctly in Mesa 9.0. The commit below introduced
the bug.

Note: This is a candidate for the 9.1 branch.
