wpa-supplicant: Include wpa_supplicant.service file in package for dbus to work
The dbus service files include a reference to wpa_supplicant.service, but if it
does not exist the dbus-daemon warns:
[system] Activating via systemd: service name='fi.w1.wpa_supplicant1' unit='wpa_supplicant.service'
[system] Activation via systemd failed for unit 'wpa_supplicant.service': Unit wpa_supplicant.service failed to load: No such file or directory. See system logs and 'systemctl status wpa_supplicant.service' for details.
If this happens, wpa_supplicant is not run automatically.
