[PATCH v4 01/13] kbuild: add install target

[Ahmad Fatoum <a.fatoum@pengutronix.de>]

For CI, it would be useful to have the barebox build install the
artifacts into a directory. Add an install target that does this.

Example usage: make install INSTALL_PATH=install/

Unlike Linux, we don't set INSTALL_PATH to a default value, because
most barebox-enabled boards don't have barebox in a file system.
