feat(build): allow to test-install the built packages

This change introduces the new --install-to-host 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.

BREAKING CHANGE: the --install flag is renamed to --install-to-chroot
to avoid confusion with the newly introduced flag.
