vc4: Avoid loading undefined (newly-allocated) FBO contents.

Since X has undefined contents in new pixmaps, it will allocate new
textures for an FBO and draw to them without an explicit clear.  For
VC4, it's much faster to emit a clear than the load of the actual
undefined memory contents, so just do that instead.
