[Buildroot] [git commit branch/2018.05.x] systemd: Fix polkit build order

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=16356507ea38e68c5504e0c3fe26fe1e2206e888
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.05.x

We need to install polkit before systemd if we want to enable
polkit integration, because systemd will not install polkit
policy files unless it finds polkit-gobject-1.
