contrib/plugins: add compat for g_memdup2
We were premature if bumping this because some of our builds are still
on older glibs. Just copy the compat handler for now and we can remove
it later.
Fixes: ee293103b0 (plugins: update lockstep to use g_memdup2)
Resolves: https://gitlab.com/qemu-project/qemu/-/issues/2161
