mesa: fix up GLSL version when computing GL version
In some situations it is convenient for a driver to expose a higher GLSL
version while some extensions are still incomplete. However in that
situation, it would report a GLSL version that was higher than the GL
version. Avoid that situation by limiting the GLSL version to the GL
version.
