weston-ivi-config-modello: update TLM configuration

Once TLM login is enabled, weston-ivi configuration files
are provided by tlm-config-ivi-*. However, to minimize
the changes during the TLM enablement, just abuse existing
weston-ivi-config-modello package to finish necessary
config changes.

FIXME: all weston-ivi* will go away soon. However, before
that, the modello config changes need to be moved into,
e.g., tlm-config-ivi-singleseat-modello.
