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.

v1 -> v2:
do work in _mesa_compute_version, not in compute_version
only fix up core profile (easier and this situation doesn't come up for
compat)
