meson: Define qemu_moddir correctly

We can't hardcode /usr here, because the user might have
configured whatever arbitrary prefix.

Everything appeared to be okay because when joining paths
Meson will drop any component that precedes an absolute path
and libdir happens to be absolute, but we should still do
things correctly instead of relying on this.
