Great. So it seems like we just need a function early in QEMU startup
that enumerates all shared libraries in QEMU_MODULE_PATH and opens them
with G_MODULE_BIND_LOCAL.
Perhaps in the future we'll load modules on-demand to avoid reduce
footprint, but for now we can just load all of them just like you get
when you build a QEMU binary with everything included.
