xrand_cycle: don't try setting resolutions that don't work

The long-lasting problem was that xrandr listed resolution it could not set. The resolutions in question are ones that use DoubleScan (due to their _usual_ low pixel count each row is scanned twice so the refresh frequencies are not bonkers). This patch changes how xrandr_cycle polls for available modes from xrandr, so we can not take into consideration the DoubleScan modes. The modes that are not filtered out should be valid modes that xrandr can use. Fixes: LP: #1627581
