pushimage: add support for signing accessories images

'accessory_usbpd' and 'accessory_rwsig' are used to sign standalone
accesory MCU firmwares (right now, the former are all the USB type-C
accessories: e.g. Zinger power supply, DingDong and HoHo display
dongles, the latter is the Smaug wireless keyboard).
