test: port 32 command/repository/downloader tests

Add create_installed_json/create_composer_lock test helpers. Port command (8),
repository path/forgejo/perforce/vcs (11), and fossil/hg/download_manager (13)
tests. Fix production porting bugs: root_package_loader/forgejo_url/version_bumper
regex delimiters, repository_manager create_repository_by_class, array_loader
isset, licenses_command RefCell borrow; implement disk_free_space and
touch2/touch3 via libc.
