site: install ffac-eol-ssid on all devices

[grische]

As this branch only builds for legacy devices, it is safe to assume that all devices installing firmware here need updating.

Coll that no device complaint about filesizes! :)

@maurerle the ffac-eol-ssid was already installed in most EOL devices, see

site-ffm/contrib/genpkglist.py

Lines 268 to 271 in c1b46e6

	for target in ['ar71xx-tiny', 'ramips-rt305x']:
	targets.get(target). \
	add_pkglist(PKGS_EOL)

This PR makes sure that ALL devices have the EOL-SSID, as no one should install the legacy-branch firmware on a device that has proper stable firmware.

To enable auto-updates for legacy+stable devices, we will be using this:

Yes, looks good. I did not look to deep into the github-downloader though.

Not the topic here, but in FFAC we have different paths for different release branches:
So updates for v2023.1.x based firmwares are fetched from http://updates.freifunk-aachen.de/from-2023.1.x/stable/sysupgrade - which contains the latest recommended images

Old branches can get updates from http://updates.freifunk-aachen.de/from-2021.1.x/stable/sysupgrade
Or I can symlink the from-2023.1.x firmware to the upgrade folder of from-2021.1.x to let all possible devices update to the latest release if possible.

But merging things into one download dir probably works too :)
