glsl: add the tessellation extension to the list for the "layout" qualifier

This is technically not needed, but it makes the compiler return a better
error message if tessellation is used with GLSL < 1.50.
Instead of:
error: syntax error, unexpected NEW_IDENTIFIER, expecting $end
It returns:
error: #version 150 layout qualifier `triangles' used
And the tessellation spec says:
OpenGL 3.2 and GLSL 1.50 are required.
So it makes perfect sense.
