systemd: Set the default firmware path to enable firmware loading in udev

After some breakage in udev the kernel gained direct firmware loading.
For older kernels (e.g. 3.2 in my case) udev still needs to load the
firmware. Firmware loading is enabled once a default firmware path is
set. Apply a compile fix from the upstream project.
