Add complete for shell by shtab

[Freed-Wu]

❯ you-get --print-completion bash | sudo tee /usr/share/bash-completion/completions/you-get
❯ you-get --print-completion zsh | sudo tee /usr/share/zsh/site-functions/_you-get
❯ you-get --print-completion tcsh|sudo tee /etc/profile.d/you-get.completion.csh

Because shtab's bug for zsh, I temporarily fix it and sent a PR to shtab. A
fixed version:

❯ you-get --print-completion zsh | xsel -ib
#compdef you-get
