tests/kms_force_connector_basic: Add prune-stale-modes subtest
Add a new subtest that makes sure old stale modes get pruned from the
connector's mode list when the EDID changes.
v2: s/drmModeGetConnector/drmModeGetConnectorCurrent/ since
kmstest_force_edid() already takes care of doing the heavier
call for us (Daniel)
