uutils: enable shell completions

Browse source 
This adds a hidden `completion` subcommand to coreutils. When invoked with
`coreutils completion <utility> <shell>` a completion file will be printed
to stdout. When running `make install` those files will be created for all
utilities and copied to the appropriate locations.
`make install` will install completions for zsh, fish and bash; however,
clap also supports generating completions for powershell and elvish.

With this patch all utilities are required to have a publich uu_app function
that returns a clap::App in addition to the uumain function.
