armbian-install: use consistent logfile name and align the according /usr/lib folder name (#5340)

* armbian-install: The log file should be named identical to the originally called install script

- the log file should be named as:
  - /var/log/armbian-install.log if script armbian-install was originally called
  - /var/log/nand-sata-install.log
- same for directory /usr/lib/nand-sata-install:
  - rename this directory to /usr/lib/armbian-install
  - create a symbolic link nand-sata-install to this folder for backward compatibility
    in a subsequent commit
- abort script armbian-install with an error message:
  - if file ${EX_LIST} does not exist
  - if dir ${BOOTLOADER} does not exist
- remove the "beta" from the version title of armbian-install

* Add symlink /usr/lib/nand-sata-install to /usr/lib/armbian-install
