Indications are that if the colormask indicates a single bit set on
fermi, that value will always be read from $r0 instead of a potentially
higher register (if e.g. green is set). Not to upset the counting logic,
always set the header up with a full color mask for each RT.
Fixes the following piglit:
fbo-stencil blit GL_DEPTH32F_STENCIL8

Needs a piglit run on both fermi and kepler just to make sure.
