pkgctl build: allow to test install the created packages

this introduces the new --install-into-host/-i flag to pkgctl build, which can be used with one of the modes 'all' or 'auto'. Depending on the mode either all or just already installed packages are installed to the host system.

This also renames --install to --install-into-chroot and adds shell completion while we are at it.

Closes #156 (closed)
