Adding dbus_display1 to util_ss ensures that the source will be linked
with audio/dbus. It also avoids recompilation when linking with
dbus-display-test.

Adding dbus_display1 to genh ensures that dbus-display1.h is generated
before compiling ui/dbus, audio/dbus, and dbus-display-test.

Both changes combined, it is no longer necessary for ui/dbus, audio/dbus,
and dbus-display-test to explicitly state the dependency on
dbus_display1.

Fixes: 142ca628a733 ("ui: add a D-Bus display backend")
Fixes: 739362d4205c ("audio: add "dbus" audio backend")
