feat: Use deb822 APT source for armbian-config

[blieque]

Replace creation of armbian-config.list with armbian-config.sources. This holds the same information in a newer format, deb822. APT has supported this format since version 1.1, released in 2015.

This does not affect armbian.list.

Something ain't right.

schwar3kat:tchncs.de My local armbian build compiles are failing near the end like this:
Command failed, retrying in 5s [ chroot_sdcard_apt_get_update ]
E: Invalid value set for option Signed-By regarding source https://github.armbian.com/configng/ stable (not a fingerprint)
E: The list of sources could not be read.
Command failed, retrying in 5s [ chroot_sdcard_apt_get_update ]
Command failed 3 times, giving up [ chroot_sdcard_apt_get_update ]
