AK3: block=auto and flash_generic improvements

- restore block=auto covering both ramdisk and boot, with ramdisk list favored to accomodate init_boot
- favor mapper/by-name in flash_generic
- add block/by-name over bootdevice/by-name in flash_generic to mirror block=auto/<name> path finding behavior
