glsl: disable lower_fragdata_array() for NIR drivers

Browse Source 
This function was added in 7e414b5864 to work around a defect in
lower_output_reads(). As of the previous commit no NIR driver calls
lower_output_reads().

This change means we don't need the special GLSL IR style
gl_FragData handling for building the resource list in a NIR based
linker.

No shader-db change on SKL i965.
