config: drop legacy 'inputd -A 2' rootfs invocation (v6.0)

The initfs already starts inputd (in phase 1) and registers the
'scheme input/evdev'. The rootfs 29_activate_console.service was
calling 'inputd -A 2' from minimal.toml, which the v6.0 inputd
binary does not accept (no -A flag; v6.0 inputd is a pure scheme
daemon that registers the single-producer evdev ring buffer).

Override the rootfs service with a no-op ('true') that satisfies
the unit dependency chain without re-spawning inputd. The actual
input pipeline (drivers writing Linux evdev, evdevd reading from
the scheme, libinput/KWin consuming /dev/input/eventN) works
without this redundant rootfs invocation.
