allow changing the dbus config file name

hsitter · hsitter · commit 4ab6ab1b7861 · 2015-04-14T10:50:00.000+02:00
on some distributions the generic name of the dbus config might be provided
by more than one display manager, so always installing with the generic
name would require distributions to hard-patch the cmake code.
allowing to change it through a cmake cache variable enables distributions
to simply parameterize in their cmake call.

this for example affects Ubuntu where the config would be provided by both
SDDM and LightDM.
