RISC-V: Fix incorrect disassembly for addiw
This fixes a bug in the disassembler constraints used
to lift instructions into pseudo-instructions, whereby
addiw instructions are always lifted to sext.w instead
of just lifting addiw with a zero immediate.

An associated fix has been made to the metadata used to
machine generate the disseasembler:
