Make auto-updates work on kickstart-static64 installs. (#7704)

* Store only the options for reinstall, not the full command.

This simplifies handling of updates with the static installer.

* Properly utilize the updater for static installs.

* Disable auto-updater when using local files.

If using local files, we can probably assume a system without a network
connection, so don't enable the auto-updater.

* Document support for auto-updates from kickstart-static64

* Fix infinite loop in auto-update option.

* Update kickstart-static64 checksum in docs.

* Remove unnecessary `sed` argument.

 -   The static binary files are kept in repo [binary-packages](https://github.com/netdata/binary-packages). You can download any of the `.run` files, and run it. These files are self-extracting shell scripts built with [makeself](https://github.com/megastep/makeself).
 -   The target system does **not** need to have bash installed.
 -   The same files can be used for updates too.
+-   If the `--local-files` option was not specified, installs `netdata-updater.sh` to `cron.daily`, so your Netdata installation will be updated daily (you will get a message from cron only if the update fails).
