test: port HgDriverTest and RootAliasPackageTest

HgDriver::supports and RootAliasPackage setRequires pass. The other Hg cases
need an HgDriver instance (HttpDownloader/curl, mocked process); the other
RootAliasPackage setters only update alias_of, not the alias's own copy, so
those getters stay empty. All such cases ignored. setUp/tearDown not ported.
