cogl/winsys-glx: Request 2 stencil bits
Just like we do on EGL. Two bits are required because
`cogl-clip-stack-gl.c` needs each stencil buffer element to be able to
count from 0 to 2.
This mistake probably went unnoticed because:
* Drivers usually provide more than 1 anyway; and
* Optimizations in `cogl-clip-stack-gl.c` avoid calling the code that
needs to count past 1 in most cases.
