base-files: sysupgrade: fix handing get_image unpack commands
On bcm53xx and brcm47xx, commands are passed to default_do_upgrade that expect the image to be passed on stdin, rather than as an argument. Fixes: 30f61a34b4cf ("base-files: always use staged sysupgrade") Signed-off-by: Matthias Schiffer <mschiffer@universe-factory.net>
