bareboxTools: init at v2020.12.0

This adds the bareboxTools as a package. The buildBarebox function is
intentionally modeled like the buildUBoot function, which should allow
future expansion to build barebox for NixOS systems. The tools are
useful on their own, since they allow flashing of systems via the
different USB loader tools shipped in the scripts directory.
