No, it doesn't.  Without your patch, Mesa successfully compiles the
following shader:

#version 130
centroid in float foo;

which is of the form "centroid in type variable".  Chris is right - the
specs are very clear that 'centroid in' was a storage qualifier, and if
420pack is enabled, 'centroid' becomes an auxiliary storage qualifier.
