mesa: fix glGetInteger/Float/etc queries for vertex arrays attribs

The vertex array Size and Stride attributes are now ubyte and short,
respectively.  The glGet code needed to be updated to handle those
types, but wasn't.

Fixes the new piglit test gl-1.5-get-array-attribs test.

v2: fix inadvertant whitespace change, change COLOR_ARRAY_SIZE to UBYTE,
misc fixes suggested by Justin
