fix(pkgctl clone): fix --maintainer and --universe being stuck

Anything that requires user input (such as a key unlock or hostkey verify) will block the terminal and wait for input which will never come.
We therefore handle just the first element without parallel so these things can easily be done.
Afterwards users are expected to either have setup a ssh ControlMaster or use something like a ssh agent.

fixes archlinux/devtools#148
