sim: sh: enable -Werror everywhere

With most of the warnings fixed in interp.c, we can enable -Werror
here too now.  There are some -Wmaybe-uninitialized warnings still
lurking that look legitimate, but we don't flag those are fatal,
and I don't have the expertise to dive into each opcode to figure
out the right way to clean them up.
