2024-12-09 install.sh - master branch

This PR follows on from discussion in SensorsIot#651 at
[@6ffm70](SensorsIot#651 (comment))
post and later.

Previously, the `backups` and `services` folders were only created if
the `~/IOTstack` folder had just been cloned.

As well as "installing", the install script should also function as a
"repair" script so it is preferable to always create the `backups` and
`services` directories and ensure that they, and their contents,
have correct ownership.
