 - Application decides to use the same name for an object of the same

glsl: Don't add nir files to libglsl_la_SOURCES

SCons doesn't understand nir yet and doesn't want to compile the glsl to
nir pass. Move the files to their own variable so we can add it only for

The scope of libi965_compiler.la is to be able to take nir shaders and
generate i965 EU code.  As such, we don't want the GLSL IR lowering
