    Move systemd services to session slice
    
    This puts all gvfs systemd services (which are all dbus-activated through
    `SystemdService=`) inside of the `session` slice that was introduced in
    v249 (https://github.com/systemd/systemd/pull/16603) and described in
    https://systemd.io/DESKTOP_ENVIRONMENTS/ and `systemd.special(7)`
    
    This allows sysadmins or OS integrators to assign higher-priority
    `systemd.resource-control(5)` on `session.slice` and have it propagate
    down to important session services such as gvfs, so that the gvfs daemons
    receive sufficient priority for resource allocations to keep the session
    running smoothly under load.
    
    Note that it still works on older systemd
    (the slice, which is just a cgroup inner directory, is created on demand)
