mesa: Set minimum possible GLSL version
Set the absolute minimum possible GLSL version. API_OPENGL_CORE can
mean an OpenGL 3.0 forward-compatible context, so that implies a minimum
possible version of 1.30. Otherwise, the minimum possible version 1.20.
Since Mesa unconditionally advertises GL_ARB_shading_language_100 and
GL_ARB_shader_objects, every driver has GLSL 1.20... even if they don't
advertise any extensions to enable any shader stages (e.g.,
GL_ARB_vertex_shader).
Converts about 2,500 piglit tests from crash to skip on NV18.
