extras: add mksboarchive helper to build SBo tarballs on demand

mksboarchive <package> builds the same <package>.tar.gz the post-commit hook
produces, but on demand by name. It validates the package, strips any sbodl
source symlinks, and archives to $OUTPUT (default: CWD). Documented in the
root README.
