cmake: Add helper to find dbus package

Browse source 
The DBus library is a message bus system used to make applications
communicate with each other.  The primary reason for adding it is to
access certain service features to prevent computer sleep/hibernate/etc.

This will also create a HAVE_DBUS variable (set to 1 or 0 if found or
not found)
