systemd: use runstatedir

On newer versions of systemd, there is an expectation that `/run` is used instead of `/var/run`. The current service file template can result in the following error message in the service: ``` systemd[1]: /lib/systemd/system/usbmuxd.service:7: PIDFile= references a path below legacy directory /var/run/, updating /var/run/usbmuxd.pid → /run/usbmuxd.pid; please update the unit file accordingly. ``` Prefer the `@runstatedir@` over `@localstatedir/run@` pattern as suggested by [1].
