Richard Henderson db770a206c meson: Move -fsanitize=undefined into normal configuraton 
With 8e466dd092 and 23ef50ae2d, we disable function pointer
sanitization in CI because the qemu code base does not support it.
We must disable this for normal usage of --enable-ubsan as well,
so move it there.

Append options rather than prepend, since all of this requires
proper ordering of options.
