gpu/kms: Report that we can have outputs if we have connectors

As part of https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/525
(introduction of transactional KMS API), the logic determining whether a
GPU can have outputs was changed from whether any connectors existed to
whether any connected connectors existed. That effectively meant that we
wouldn't attempt to start at all if there were no monitors connected
while starting up.

This was unintentional, so lets revert back the expected behavior.
