riscv: alternative: proceed one more instruction for auipc/jalr pair
If we patched auipc + jalr pair, we'd better proceed one more
instruction. Andrew pointed out "There's not a problem now, since
we're only adding a fixup for jal, not jalr, but we should
future-proof this and there's no reason to revisit an already fixed-up
instruction anyway."
