futility: Adds platform check quirk for zork

Adds a quirk for futility on zork boards.
Zork boards before 13073 used lowercase for the firmware
names which causes the compatible platform check fail.

This adds the disable_compatible_platform_check quirk and
enables it by default for zork boards.

BUG=b:156119908, b:155941790
TEST=flashed Google_trembyle.13066.0.0 using servo
     chromeos-firmwareupdater --force
     rebooted and confirmed Google_Trembyle.13073.0.0 was flashed
BRANCH=none
