nixos/nextcloud: add nextcloud-update-db.service, nextcloud-cron isn't oneshot

This service performs operations that significantly increase the
performance of Nextcloud, can take a while. These are designed however
to not require maintenance mode and can be executed during normal
operation[1].

Make nextcloud-cron a simple unit instead of oneshot: otherwise we risk
that it'll be stopped by the startup timeout (oneshot executes ExecStart
while "activating") which can be an issue for very long running tasks or
if Nextcloud needs to catch up if one task was broken for a while.
