Subject: [PATCH] ubuntu-ports: Fix sed in Armbian env

Works like ba48848a513a366cb7abecccbed3c8d735a0dc55 and replaces #257

DEB822 sed is not replaced -- Armbian is not using DEB822 now (https://github.com/armbian/build/blob/ec8c470da3f3fa60d0b4fba2e3e7b07610c5f859/lib/functions/rootfs/distro-specific.sh#L86)
