dbus: Rename D-Bus autostart service file name

The autostart file needs to match the service name according the D-Bus
specification [1]:

"""
The service filename of "org.me.test.service" is then searched for
in /usr/share/dbus-1/system-services or other specified directories.
"""

This fixes "Bus name not found in system service directory".
