mediatek: filogic: fix EAX17 rootfs hash in FIT node for per-device rootfs builds

When CONFIG_TARGET_PER_DEVICE_ROOTFS is enabled (as in buildbot builds),
the final per-device rootfs is assembled at root.squashfs+pkg=<hash> rather
than root.squashfs. The gen_netgear_rootfs_node.sh script was always hashing
root.squashfs (the base rootfs without device-specific packages), causing the
size and hash in the FIT node to not match the actual rootfs written to the
UBI volume, resulting in boot failure on buildbot-produced images.

Fix by using the per-device rootfs path when TARGET_PER_DEVICE_ROOTFS is set,
consistent with how include/image.mk handles the same distinction elsewhere.
