Allow to install klippain-shaketune in a given directory.

[tsk-2222]

Based on @arcadien's work on klippain. Thanks arcadien!

example: ./install.sh voron_2 or ./install.sh printer_8

Additionally, this needs an override or to be handled somehow:

[gcode_shell_command shaketune]
command: ~/printer_data/config/scripts/K-ShakeTune/shaketune.sh

If this script is acceptable, I also have the changes for klippain that are very similar.
