William Giokas 4f87c47b35 zsh_completion: fix zsh completion installation ...

Moved zsh shell completion to shell-completion/zsh/_systemd for
automake's sake. Also allow users to specify where the files should go
with::

  ./configure --with-zshcompletiondir=/path/to/some/where

and by default going to `$datadir/zsh/site-functions`
