test: port package archiver/loader/version/locker and PluginInstaller stubs

All ignored: ArrayLoader/ValidatingArrayLoader/VersionSelector parse
constraints via a look-around regex; ArchiveManager uses PharData (todo!());
ArchivableFilesFinder/VersionGuesser/Locker mock git/process/IO; the plugin API
is not implemented (TODO(plugin)). Wires up the plugin test target.
