Subject: [PATCH] dbus: fix install name on installed binaries
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some binaries have incorrect install names. They should be the absolute
path, but they have `@rpath` instead. This something that Meson should
handle automatically, but it’s not happening for these binaries.
