i965/fs: Mark UBO uniform pull constant loads as force_writemask_all.

This lets the rest of the backend know that the uniform pull constant
load opcodes don't respect channel enables -- Without this the
register allocator has no way to know that the return payload of a
pull constant load is not per-channel and spills of the destination
will be broken under non-uniform control flow.
