[sysprof/wip/chergert/sysprof-3] libsysprof-ui: stub out proxy source

commit 6a65f57bc5e98f86c1fcb2c538aeb197035b662c
Author: Christian Hergert <chergert redhat com>
Date:   Sun May 19 22:46:22 2019 -0700

    libsysprof-ui: stub out proxy source
    
    The goal for this (which is unfinished) is to setup a dbus proxy to the
    peer. That can be reused for both gtk and mutter, if configured correctly.
    
    We'll likely need to allow some specific config tweaks in the UI.
