ath79: fix rootfs padding for D-Link DAP-2xxx

It was observed that `rootfs_data` was sometimes not correctly erased
after performing sysupgrade, resulting in previous settings to prevail.

Add call to `wrgg-pad-rootfs` in sysupgrade image recipe to ensure any
previous jffs2 will be wiped, consistent with DAP-2610 from the ipq40xx
target, which introduced the double-flashing procedure for these devices.
