home: services: niri: Use existing session dbus.

Browse Source 
Spawning niri with `dbus-run-session` as is done here causes the compositor
and children applications to run within it's own D-Bus session bus rather than
relying on the already existing one.  This causes Guix home services that rely
on a session bus to misbehave within a niri session, as the bus the services
are talking to is not the same as the one niri & applications see.  Guix home
already provides a `home-dbus-service-type` for ensuring a D-Bus session bus
exists, so it makes sense to just rely on that.

* gnu/home/services/niri.scm (home-niri-service-type): Add
HOME-DBUS-SERVICE-TYPE extension.
(home-niri-shepherd-service)[requirement]: Add DBUS requirement.
[start]: Drop the 'dbus-run-session' call in favour of extending
HOME-DBUS-SERVICE-TYPE.
