[PATCH] systemd: Update service files according to dbus interface version used

[Marcin Niestroj]

systemd service files were supplied with old DBus bus name. After
service activation systemd was waiting for appearance of specified bus
name to consider it started successfully. However, if wpa_supplicant was
compiled only with new dbus interface name, then systemd didn't notice
configured (old) DBus bus name appearance. In the end service was
considered malfunctioning and it was deactivated.

Update systemd service BusName property according to supported DBus
interface version.
