tests/kms_force_connector_basic: Add prune-stale-modes subtest

Browse Source 
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)
