Improvements and bug fixes to Armbian user-space services (#6840)

* Add a list of BASH shell aliases and merge them with ohmyZSH aliases
* Add command armbian-upgrade to the BSP which executes update + upgrade
* Display armbian-upgrade only if there are upgrades
* Generate empty folder where will store data. This doesn't exists at early start
* Move armbian-install to /usr/bin and autoexecute sudo
