tests/kms_chamelium: Force reprobe after replugging the connector

After replugging a connector and the kernel reports the connector as
connected the cached modes returned by drmModeGetConnectorCurrent() (the
kernel's cached list of modes) may be stale. The modes will be only
updated by a full reprobe. Ensure this by setting output->force_reprobe
which will result in calling drmModeGetConnector().

This fixes sporadic test failures due to seeing no modes unexpectedly.
So far things happened to work, because some in-kernel user of the
output - like fbdev - does a full reprobe sometime after the hotplug
event.
