Try booting up to 3 times on GRUB2 based systems (#2112)

Browse Source 
* Retry up to 3 times

By default, HAOS used to retry 3 times. That is still true for U-Boot
based boards. Apply the same logic for GRUB2 based systems for
consistency.

This can help to remedy intermittent internet/connectivity issuese.
Altough hacky, in practise it makes sense to give the newly installed OS
another go.

* Also apply to generic-aarch64
