feat: name only a missing base64; lldpd, auc and updates are facts (0.3.0)

get_device_warnings no longer names lldpd_not_installed,
updates_available or update_notifications_disabled. The packages and
get_available_updates are the facts; netOrk derives the warnings with the
same reach (netOrk #1111). The old update read swallowed failures,
get_available_updates raises them.

no_base64 stays: BusyBox may provide base64 as an applet, so no package
tells the caller whether it is there.
