Fix tix archive owner, group and permissions.

tix-build recorded the owner and group as the user building the package,
rather than setting the owner and group to user 0 (root).

tix-install tried to chown extracted files as the owner and group in the
archive, rather than the current user. It also applied the current umask
rather than restoring the same permissions.
