shader: keep root table reads the blit constants would zero

Fire Emblem: Fortune's Weave's enemy health gauges read only offset 0x40
of root table 0, which is inside the blit parameter block (title 4's
zero dither bias). The pass replaced it with zero and the gauges drew
black. A shader that reads only words the block leaves zero now keeps
its reads: an unbound bank reads zero anyway, and a bound root table
keeps its values.
