Move scripts to .local/bin

Moved all personal scripts to ~/.local/bin to be systemd file hierarchy
compliant, as well as XDG compliant. Since they are not configuration
options they don't have anything to do in .config directories.
Also, it's just easier to find than the previous .config/scripts/bin.

.config/shell/login.d/dotfilescripts.sh
