* Fix path to bind9 startup options file in Ubuntu 22.04.

* Upgrade Vagrant box to Ubuntu 22.04
We install b2sdk in two places: Once globally for duplicity (see
9d8fdef9915127f016eb6424322a149cdff25d7 for #2125) and once in
a virtualenv used by our control panel. The latter wasn't pinned
when the former was but should be to fix new Python compatibility
issues.
Anyone who updated Python packages recently (so anyone who upgraded
Mail-in-a-Box) started encountering these issues.
Fixes#2131.
See https://discourse.mailinabox.email/t/backblaze-b2-backup-not-working-since-v57/9231.
Update jails.conf to include IPV6 localhost and external ip to ignoreip line. Update system.sh to include IPV6 address in replacement. See mail-in-a-box#2066 for details.
See [mailinabox issue #2088](https://github.com/mail-in-a-box/mailinabox/issues/2088). This also updates the commit hashes to for anyone updating from NextCloud version 17 (as shown in the related issue) since a different hash is used for tags vs releases.
This was tested and verified to work on a setup previously running v0.44 and then updating to the latest version (v56).
1. `systemctl reload postgrey` is broken, so use restart in that case
2. `systemctl restart nsd` succeeds once /var/log is writable by systemd. However, nsd still fails to write to /var/log/nsd.log if the file already exists
3. the default configuration for rsyslogd is to no longer create a /var/run/rsyslogd.pid file, so use /usr/bin/pidof in that case
The first version supporting PHP 8.0 is Nextcloud 21. Therefore we can add migrations only to Nextcloud 21 forward, and so we only support migrating from Nextcloud 20 (Mail-in-a-Box versions v0.51+). Migration steps through Nextcloud 21 and 22 are added.
(Updated by @JoshData from the original commit which was for Ubuntu 20.04 using PHP 7.4. And although 8.1 seems to be available, it's not supported by Nextcloud yet, and it likely will never be supported by the the version of Nextcloud that succeeds the last version of Nextcloud that supports PHP 7.2, and we have to install the next version so that an upgrade is permitted, so skipping to PHP 8.1 may not be easily possible.)
